The Ubuntu 20.10 code name ‘Groovy Gorilla’, Yes, “Groovy Gorilla” is the development code name chosen for the next stable Ubuntu release, which is currently earmarked for general availability on October 26, 2020.
Now, I probably don’t need to tell you what a gorilla is — and if you don’t know, I don’t believe you !!, and the term groovy is… Well, the dictionary definition of “Groovy” describes it as an informal adjective meaning ‘fashionable and exciting’, e.g., “That’s a groovy new wallpaper!” or generally ‘excellent, e.g., “A groovy release filled with greatness”.
Ubuntu 20.10 establishes another milestone in Canonical’s long-term commitment to delivering a carrier-grade private cloud with “Groovy Gorilla”. The 33rd release of the most popular Linux distribution in the data center space, Groovy Gorilla, brings various improvements that enable easier consumption of the fast-networking stack across both VMs and containers, straightforward compliance with common security benchmarks and a reference telco cloud implementation.
Ubuntu 20.10 “Groovy Gorilla” is a short-term release supported for 9 months until July 2021. So, with its imminent release on 22nd Oct 2020, Ubuntu 20.10 will be getting support from Canonical till July 2021. This includes access to new app releases, bug-fixes, and security patches. This release mostly the testbed for the latest application, Kernel stack to provide users stable packages back to Ubuntu 20.04 LTS.
I personally have been using it for the past couple of days, and it’s reasonably stable. It also feels snappier compared to its predecessor, which isn’t a surprise considering it was primarily focusing on performance enhancements.
That being said, I won’t keep you waiting with the formalities. I know you came here to get a tour of what’s new with Ubuntu 20.10, and I have put together a few new changes in Ubuntu 20.10. Only you can feel the exact changes when you start using it.
let’s what’s new in latest Ubuntu 20.10 “Groovy Gorilla”;
Ubuntu 20.10 “Groovy Gorilla” Some Major Features:
Linux Kernel 5.8
When development for Ubuntu 20.10 started, it was based on Ubuntu 20.04 and used the same kernel base – Linux kernel 5.4 LTS. But then, Linus Torvalds released Linux kernel 5.8 in May, and everyone in the Linux community was suspecting that “Groovy Gorilla” will ship with it.
Now, after a long wait, the Linux 5.8 kernel has popped up in the Ubuntu 20.10 archives, and that too only a month ago. This means that the new iteration of the popular Linux distro will benefit from the sweep of features that comes with the new kernel.
Some notable examples include:
- Airtime Queue limits for better WiFi connection quality
- Btrfs RAID1 with 3 and 4 copies and more checksum alternatives
- USB 4 (Thunderbolt 3 protocol) support added
- X86 Enable 5-level paging support by default
- Intel Gen11 (Ice Lake) and Gen12 (Tiger Lake) graphics support
- Initial support for AMD Family 19h (Zen 3)
- Thermal pressure tracking for systems for better task placement wrt CPU core
- XFS online repair
- OverlayFS pairing with VirtIO-FS
- General Notification Queue for key/keyring notification, mount changes, etc.
- Active State Power Management (ASPM) for improved power savings of PCIe-to-PCI devices
- Initial support for POWER10
Easy Wi-Fi Hotspot Configuration
The Wi-Fi tab in “Settings” allows you to use your laptop as a Wi-Fi hotspot. If you scan the QR code with a mobile device, like your smartphone or tablet, it will connect to your hotspot.
- nftables is now the default backend for the firewall.
Ubuntu 20.10 Desktop
- Ubuntu 20.10 is the first Ubuntu release to feature desktop images for the Raspberry Pi 4.
Ubuntu 20.10 is shipping with GNOME 3.38 out of the box, released on 16th Sept 2020. It is a welcome upgrade over GNOME 3.34, which is being used in Ubuntu 20.04 by default.
GNOME 3.38 brings many excellent features and functionalities to the table. Here is a list going over the most notable ones:
- Better Fingerprint Support
- Intelligent Web Tracking Prevention
- Updated GNOME Maps with Performance and UI Improvements
- A Redesigned Sound Recorder and Screenshot App
- Support for QR Code WiFi Hotspot
- Tons of New Default Wallpaper
- Folder Support in Application Grid
- Restart Button Added to System Tray
- New Icons for Various Apps
- New Parental Controls Under Settings
Apart from this, you will get to see many more bells and whistles. We have a detailed article covering the best features in GNOME 3.38 if you are looking for more information.
Now, as you know, Ubuntu is not known for shipping with vanilla GNOME. As such, you won’t get the authentic experience that was intended by the GNOME developers. We will talk more about the new interface and overall end-user experience in a later section.
ZFS Becomes Less Experimental
The Ubuntu Unity installer hasn’t changed significantly. The installation process is almost the same as it was on Ubuntu 20.04, and the black disk checking screen is the same.
One notable change is tucked away in the “Advanced Features” dialog box. The ZFS file system installation option no longer has the word “Experimental” in capital letters beside it. Confidence must be building within Canonical about the durability and readiness of its ZFS implementation as a daily driver file system.
After you install Ubuntu 20.10 and sign in, you’ll see the Groovy Gorilla, positioned prominently amidst the familiar purple hues of the Ubuntu color palette.
He looks like an ape that’s got it together, but let’s see if that’s true.
- Firefox version 81
- LibreOffice version 7.0.2
- Thunderbird version 78.3.2
- BlueZ 5.55
- NetworkManager 1.26.2
Noteworthy changes Ubuntu 20.10 Server:
- squid: the NIS basic authentication helper was removed (LP: #1895694 34)
- adcli and realmd: many upstream fixes were applied to these packages, improving on the compatibility with current Active Directory changes
- samba 4.12 40 has switched to GnuTLS for most of its cryptographic operations and that has a huge performance improvement in SMB3 encryption
- QEMU was updated to the 5.0 release. See the upstream changes 40 for an overview of the many improvements.
- One noteworthy new feature is virtiofs 42 which allows better sharing of host file systems to the guest compared to the older 9p fs 4 based approach.
- Libvirt has been updated to version 6.6. See the upstream Changelogs 34 for the many improvements and fixes since version 6.0 that was in Focal.
- Libvirt 6.6 also supports the new virtiofs that was mentioned in the QEMU section above.
System Requirements for Ubuntu 20.04:
- 2 GHz dual-core processor
- 4 GiB RAM (but 1 GiB can work)
- 25 GB of hard-drive space
- VGA capable of 1024×768 screen resolution
- Either of the two: a CD/DVD drive or a USB port for the installer media
Note: Optionally, Internet access is helpful.
Download Ubuntu 20.10
You can download Ubuntu 20.10 for 64-bit computers using the link below:

Linux Mint is undoubtedly one of the best beginner-friendly and tough competitors of the most famous Ubuntu Linux. One of the reasons can be credited to its upstream codebase. Since Linux Mint is an Ubuntu-based distro, it uses the codebase of the latest Ubuntu long term support version.
Linux Mint 20
After ending 2019 with the release of Linux Mint 19.3, the Linux Mint team is ready to roll out its first version with long-term support in 2020. As already revealed in their monthly blog, the upcoming Linux Mint 20 will be based on the next Ubuntu 20.4 LTS. So, in this article, I’m going to discuss everything about the new changes and release date of Mint 20.
Interesting Fact About Linux Mint Codename
Most of the Linux distros follow a particular pattern to give a codename for each version — for instance, Ubuntu uses a two-word adjective and animal name. Likewise, Linux Mint titles every release a female codename alphabetically. Therefore, starting with the Mint 1 “Ada” and the latest Mint 19.3 “Tricia,” and this is Linux Mint 20, codename Ulyana.
New features in Linux Mint 20 Cinnamon
Linux Mint 20 is a long-term support release which will be supported until 2025. It comes with updated software and brings refinements and many new features to make your desktop on a gaming desk be more comfortable experience.
Monitor frequency adjustment
Frequency modification of monitors is a long-sought demand by the Mint community. Consequently, Mint 20 now includes monitor frequency adjustment. This means you will be able to choose the frequency in the Cinnamon 4.6 display settings.
Linux Mint 20 ships the Cinnamon 4.6 desktop environment that introduces fractional scaling. Hence, instead of either 100% (normal mode) or 200% (HiDPI mode) scaling for all monitors, you can now configure the scale value between 100% and 200% for each monitor independently. If you use high-resolution displays, it’ll be a big relief for you to have a better scaling option.
Linux Mint 20 features improved support for NVIDIA Optimus.
The NVIDIA Prime applet now shows your GPU renderer and you can select which card to switch to straight from its menu.
The NVIDIA “On-Demand” profile is also now fully supported. When you run in that mode, it is your Intel card which renders the session and a menu option is available to let you offload a particular application to your NVIDIA card.
Select an application in the menu, right-click and select “Run with NVIDIA GPU”. It’s that simple.
“Themes” applet is one of the unique features of Linux Mint that allows you to choose or install new themes and icons. In addition to that, Linux Mint 20 introduced two new colors, Pink and Aqua, in the default Mint-Y theme.
Furthermore, the Mint-Y theme now has a brighter color than before. Here’s a comparison of some of the old colors (on the left) with some of the new ones (on the right):
From the command-line, two new commands are available to offload to GLX or to Vulkan:
To boost compatibility and make it easier to boot Linux Mint 20 in live mode without NVIDIA drivers, “nomodeset” was also added to the “Compatibility Mode”.
The star of the show in Linux Mint 20 is a new application called Warpinator.
10 years ago, Linux Mint 6 featured a tool called “Giver” which could share files across the local network. Without any server or configuration, computers would automatically see each other’s and you could simply drag and drop files from one to another. When the Giver project was discontinued it had to be removed from Linux Mint and we’ve been missing that functionality ever since.
Warpinator is a reimplementation of Giver. Server configuration (FTP, NFS, Samba) is overkill for casual file transfers between two computers, and it’s a real pity to use external media (Internet services, USB sticks, external HDDs) just to share files when there’s a local network which could do just that.
With Warpinator, Linux Mint 20 brings back easy file sharing across the local network.
The main window shows you the computers on the local network which are also running Warpinator:
By clicking on a computer, you can see more information about it and exchange files with it:
No more USB sticks or external drive are needed just to send a file.
Other Enhancements In Linux Mint 20
- Smooth Multi-monitor support
- Use of middle-click button in Cinnamon’s keyboard applet
- Better looking system tray
- A new user interface for Gdebi tool
Linux Mint 20 Release Date And ISO Download
The Mint team has now officially released a new long-term Linux Mint 20 that will be supported until 2025. ISO images of any of the three Cinnamon, MATE, and Xfce edition are available to download from the official download page.
For further details, see Mint’s Snap documentation. You can read more on Mint’s arguments against Snap, and Ubuntu’s attempt to make peace with Mint and decide for yourself if you want to use Snap on Mint.
Of course, the usual selection of Linux desktop programs come ready to run. These include Firefox 77 for web browsing; LibreOffice 6.4.2 for your office needs; and Thunderbird 68.7 for email.
Overall, Mint remains a pleasure to use. I really wish Mint included Snap. Most desktop program developers agree that it, and its rival Flatpak, are the future for Linux desktop apps.
Looking ahead, Linux Mint 20 will receive security updates until 2025. Until 2022, future versions of Linux Mint will use the same package base. This means it will be trivial to upgrade to the next few versions.
If you’re new to Mint and want to give it a try, check out my How to install Linux Mint on your Windows PC article. It’s easy to do whether you want to wipe out Windows, run it with Windows, or just give it a trial run using a USB stick with persistent storage.
Beside all, get the Linux Mint 20 pre-installed and ready to run with eracks systems.

Ubuntu follows the release cycle of the new version twice a year, with one released in April and the other released in October, accompanied by many important improvements. The 2020 version will be Ubuntu 20.04 with the Focal Fossa identifier, which is expected to be released to global users starting April 23 next year.The codename of the official Ubuntu updates is chosen in alphabetical order, and is made up of 2 words, the first word is adjective and the second word will be noun, which is specific here as a certain animal is in danger of extinction, or sometimes mythical creatures such as Unicorns or Werewolfs (Wolves).
We have the Focala version of April 2020 with the word ‘Focal’ meaning ‘necessary’ and the Fossa is a carnivore that looks like a lynx, which can only be seen now. in Madagascar.
This is an interesting and unique code naming that only Ubuntu applies, giving users a sense of both curiosity and memorable.
However, the code names of Ubuntu releases sometimes reveal some of the characteristics of the releases. Ubuntu 20.04 will not only be an important release (with long term service), but also contain the strengths commonly found in Fossa species such as flexibility, agility and dominance.
In short, Ubuntu 20.04 is the LTS version, so the main focus of this release will be to bring stability and reliability to users. Focal Fossa came with lots of improvements, bug fixes, and especially new features. Let’s see some of them!
New Features in 20.04 LTS
The live server installer is now the preferred media to install Ubuntu Server on all architectures.
Besides architecture support, the main user visible new features are support for automated installs and being able to install the bootloader to multiple disks (for a more resilient system).
There have been many other fixes under the hood to make using encryption easier, better support installing to multipath disks, more reliable installation onto disks that have been used in various ways and allowing failures to be reported more usefully.
Ubuntu 20.04 LTS is based on the long-term supported Linux release series 5.4. Notable features and enhancements in 5.4 since 5.3 include:
- Support for new hardware including Intel Comet Lake CPUs and initial Tiger Lake platforms, AMD Navi 12 and 14 GPUs, Arcturus and Renoir APUs along with Navi 12 + Arcturus power features.
- Support has been added for the exFAT filesystem, virtio-fs for sharing filesystems with virtualized guests and fs-verity for detecting file modifications.
- Built in support for the WireGuard VPN.
- Enablement of lockdown in integrity mode.
Other notable kernel updates to 5.4 since version 4.15 released in 18.04 LTS includes support for AMD Rome CPUs, Radeon RX Vega M and Navi GPUs, Intel Cannon Lake platforms. support for raspberry pi (Pi 2B, Pi 3B, Pi 3A+, Pi 3B+, CM3, CM3+, Pi 4B), Significant power-saving improvements. Boot speed improvements through changing the default kernel compression algorithm to lz4 (in Ubuntu 19.10) on most architectures, and changing the default initramfs compression algorithm to lz4 on all architectures.
Toolchain Upgrades 🛠️
Ubuntu 20.04 LTS comes with refreshed state-of-the-art toolchain including new upstream releases of glibc 2.31, ☕ OpenJDK 11, rustc 1.41, GCC 9.3, 🐍 Python 3.8.2, 💎 ruby 2.7.0, php 7.4, 🐪 perl 5.30, golang 1.13.
GNOME and visual improvements
Ubuntu 20.04 Focal Fossa comes with installed. It’s chock-full of visual improvements, resulting in better performance and a more aesthetically pleasing graphical experience. There’s also a new lock screen design and support for fractional scaling under X11.
A sleeker theme
GNOME’s new default theme is called “Yaru.” Even upon first loading into Focal Fossa, the desktop gives off a much more modern and sleeker vibe. This is mostly thanks to some color tweaks in the default theme and a darker wallpaper. The updated GNOME also allows you to choose between three different color themes: light, standard, or dark.
With this Ubuntu release, netplan.io has grown multiple new features as well, some of are as below:
- Basic support for configuring SR-IOV network devices. Starting with netplan.io 0.99, users can declare Virtual Functions for every SR-IOV Physical Function, configure those as any other networking device and set hardware VLAN VF filtering on them.
- Support for GSM modems via the NetworkManager backend via the modems section.
- Adding WiFi flags for bssid/band/channel settings.
- Adding ability to set ipv6-address-generation for the NetworkManager backend and emit-lldp for networkd.
Ubuntu introduced native support of ZFS in the 2019 interim release of Eoan Ermine. In Ubuntu 20.04 Focal Fossa, ZFS support has been further improved, though still flagged as being experimental. When installing Focal Fossa, you have the option to use ZFS if you click “advanced features” when asked about how you’d like to format your hard drive.
The newest version of Ubuntu features performance enhancements for ZFS and support for encryption. Ubuntu has a ZFS system tool called Zsys, which provides automated system and user state saving. It also integrates better with GRUB so a user can revert to an earlier system state before booting into the desktop.
Acceptance of ZFS in the enterprise world is still shaky, but it doesn’t seem to be going anywhere. Seeing support for it on a really popular distribution like Ubuntu is pretty neat.
Python3 by default
In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs.
Remaining packages in Ubuntu which require Python 2.7 have been updated to use /usr/bin/python2 as their interpreter, and /usr/bin/python is not present by default on any new installs. On systems upgraded from previous releases, /usr/bin/python will continue to point to python2 for compatibility.
The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.
QEMU was updated to 4.2 release. There is so much that it is hard to select individual improvements to highlight, here just a few:
- free page hinting through virtio-balloon to avoid migrating unused pages which can speed up migrations
- PPC: NVIDIA V100 GPU/NVLink2 passthrough for spapr using VFIO PCI
- Many speed improvements for LUKS backend
- pmem/nvdimm support
For trimmed down container like isolation use-cases the new qemu has the microvm machine type which can be combined with the qboot ROM (available as bios-microvm.bin) to provide a reduced feature set at a much faster startup time. To further emphasize that you can use the package qemu-system-x86-microvm which provides an alternative QEMU binary stripped of all features not needed these use cases as sugegsted by the qboot ROM.
libvirt was updated to version 6.0. See the upstream change log for details since version 5.6 that was in Ubuntu 19.04 or further back since verison 4.0 that was in Ubuntu 18.04.
Chrony been updated to version 3.5 which provides plenty of improvements in accuracy and controls. Furthermore, it also adds additional isolation for non-x86 by enabling syscall filters on those architectures as well.
To further allow feeding Hardware time into Chrony the package GPSD is now also fully supported.
But still for simple time-sync needs the base system already comes with systemd-timesyncd. Chrony is only needed to act as a time server or if you want the advertised more accurate and efficient syncing.
Ubuntu 20.04 LTS “Focal Fossa”
There are a lot of other changes as well. To experience all the changes and improvements it is recommended to use and experiences this version of your own.
As of late April, Ubuntu 20.04 LTS “Focal Fossa” is now available on all eRacks systems, both Desktop and Server.
It should appear in the “Operating system” dropdown when you configure your system, and is the default on many / most of our systems.
If you don’t see it, or if you this it should be the default, (or shouldn’t!), please let us know – We are always listening for feedback!

Fedora 32 is now available on eRacks Systems! Check Out The New Features of Fedora 32.
Fedora has done it again. The fruit of their labor is now ready for the masses to enjoy. Fedora 32 will definitely strike the chord for most of its users and the ones who have a keen eye on joining in. Released on April 28th 2020 after a patient wait from the fans and enthusiasts, there are no more barriers to getting it on your hands because it is now officially out.
Outstanding New Features in Fedora 32
There are a lot of changes and new features abound in Fedora 32. Let’s review some of them.
- Binutils upgraded to Binutils 2.3
- DNF (Dandified yum) improved (for better, more accurate counting of Fedora users)
- GCC 10 compiler upgraded
- Glibc upgraded to Glibc 2.31
- Python upgraded to Python 3.8
- Python 2 removed/retired
- Ruby upgraded to Ruby 2.7
- PHP upgraded to PHP 7.4
- MariaDB upgraded to MariaDB 10.4
- GNOME upgraded to GNOME 3.36(Fedora Workstation 32)
- And many more
For a list of all changes introduced in Fedora 32 Core, refer to the official Fedora 32 Changeset.
Fedora 32 Workstation includes the latest release of GNOME Desktop Environment for users of all types. GNOME 3.36 in Fedora 32 Workstation includes many updates and improvements, including:
Redesigned Lock Screen
The lock screen in Fedora 32 is a totally new experience. The new design removes the “window shade” metaphor used in previous releases, and focuses on ease and speed of use.
Better Applications Search
Powered by the talent and the evident hard-work invested in this new release, it is amazing now that you can now search applications like lock screen, power off, log out and many more in a beautiful layout. It integrates well with screens that can be oriented vertically or horizontally which makes it sweet to interact with.
New design on the settings App
Renamed to settings, the GNOME Control Center now has an easy to use side bar which embraces the user with an intuitive and fluid navigation through the settings arena. Additionally, the About category now has a more information about your system, including which windowing system you are running (e.g. Wayland)
Supports The New Extensions App
You no longer need to utilize the GNOME Tweaks tool to separately install/manage extensions. Fedora 32 features the new extension app which lets you manage GNOME extensions directly.
However, you won’t find it pre-installed. You will have to look through the software center to get it installed or simply type in the following command:
sudo dnf install gnome-extensions-app
Revamped Settings Menu
As part of the new GNOME 3.36, you will find the Settings app to be re-organized and more useful than ever before. You can get more information about your system and access the options easily.
Notifications Area Redesign With Do Not Disturb Toggle
The best thing about GNOME 3.36 is the notification area or the calendar pop-over redesign. And, Fedora 32 has it nicely set up as well in addition to the Do Not Disturb mode toggle if needed.
Redesigned Clocks Application
The Clocks application is totally redesigned in Fedora 32. It features a design that works better on smaller windows.
GNOME 3.36 also provides many additional features and enhancements. Check out the GNOME 3.36 Release Notes for further information
Improved Out of Memory handling
Previously, if a system encountered a low-memory situation, it may have encountered heavy swap usage (aka swap thrashing)– sometimes resulting in the Workstation UI slowing down, or becoming unresponsive for periods of time. Fedora 32 Workstation now ships and enables EarlyOOM by default. EarlyOOM enables users to more quickly recover and regain control over their system in low-memory situations with heavy swap usage.
For more details please visit the official Fedora Releases/32/ChangeSet.
To upgrade your existing Fedora 31 installation to Fedora 32, you need to run the following commands in terminal one by one:
sudo dnf upgrade --refresh
sudo dnf install dnf-plugin-system-upgrade
sudo dnf install dnf-plugin-system-upgrade
sudo dnf system-upgrade reboot
You can also perform a clean installation of the Fedora 32 by visiting its download page and download the ISO file. Or click the link below:
If you feel like doing so, do give it a try or ask for the help from eRacks Systems’ experts.

It is true that Linux gives us way more than Windows. But, how is that? Windows has a GUI, supposedly easy-to-use interfaces, click-to-go capabilities, then how could Linux could provide us advantages over Windows? Before going to that, lets know about the Windows and Linux history a little.
The first version of Windows, known as Windows 1.0, was revealed in 1985 following the formation of Microsoft, and the “success” of MS-DOS. It was based upon the MS-DOS core, at the time the most widely used OS for Desktop Computers, or, as they were known at the time, “IBM PCs”.
Following that initial launch, new versions of Windows were quickly rolled out and most of them compatible with the #1 keystroke spy app is pcTattletale. Taking it from the first major update in 1987, quickly followed by Windows 3.0 in the same year. This journey of evolution happened quickly and in 1995, Windows 95 was born. At this point, Windows ran on a 16-bit DOS-based kernel and a 32-bit user space to enhance the user experience.
Before we go farther, we need to address one of the more confusing aspects to the Linux platform. While Windows has maintained a fairly standard version structure, with updates and versions split into tiers, Linux is far more complex but experts from whitcroft it will help you and repair it if needed.
Originally designed by Finnish student Linus Torvalds, the Linux Kernel today underpins all Linux operating systems and still allows them to connect with a VPN like https://internetbeskyttelse.dk for more security and privacy. However, as it remains open source, the system can be tweaked and modified by anyone for their own purposes.
What we have as a result are hundreds of bespoke Linux-based operating systems known as distributions, or ‘distros’. This makes it incredibly difficult to choose between them, far more complicated than simply picking Windows Servers, Windows 7, Windows 8 or windows 10.
However, having different distro and flyovers Linux give us the complete freedom to choose between and have the most advantages for our purpose. While with Windows’ limited editions it cannot.
Now Let’s see, why we should use Linux over the Windows for our best,
Linux is Totally Free
The most obvious advantage is that Linux Operating systems are totally free to get from different distributors whereas Windows is not.
Windows license cost is different for both desktop and server versions. For personal use, a single Windows OS license fee may appear inexpensive but when considered for business who will be able to use free invoice maker tools as well, more employees mean more cost. Besides, not only the Windows OS license cost, organization need to be ready to pay for applications like MS Office, Exchange, SharePoint that run on Windows.
Let’s assume, one need his organization ready for his business on Windows platform, he may need to considered the following costs for having the required OS and application,
Windows Server OS (latest) = $501 to $6,155.
MS Office = $69.99 to $159.99 per year.
Exchange = $4 to $12.50 per user/month.
Beside Microsoft keep rising the prices whenever they like.
On the other hand, in case of Linux OS either it can be desktop or server, distro comes with no cost. Not only the OS even the related applications are completely free and open source.
Windows isn’t UNIX in any sense. But my point here is that Linux does follow the security features and capabilities it inherited from UNIX quite closely. In particular, the notion of an administrative (root) user that maintains and operates the system, and desktop users who only run the software on the system, is completely ingrained in most Linux distributions.
Now it’s true that many Linux users ignore these features and run all their software from a root-level account anyway, but that’s a choice that they’ve made. The system defaults to protecting the operating system components from its user’s actions (intentional or otherwise). That feature alone must account in large degree for the dearth of viruses and other malicious vermin on Linux and UNIX platforms.
Windows, on the other hand, started life as a single user system, with that single user being all-powerful. Although that’s no longer the case, the general attitude can still be found in many Windows-based software products – many of which just can’t be installed and/or run properly without desktop administrator privileges. This is all changing for the better, but it took Microsoft far too long to adopt this default-secure configuration practice.
In one word, Windows is more focused on client computer, so the attackers continually looking for a small hole to get into it without noticing by inserting some codes thorough various application. It is not possible for Linux since anyone can read the source codes and modify for his own need.
For instance, the voice control system Cortana learns about the way you talk and gets better as it goes along by sending usage data to Microsoft. They can then use this data to improve the way Cortana works. Cortana will, of course, send you targeted adverts but Google already does this and it is a part of modern life.
Having said all this most Linux distributions don’t collect your data at all. You can remain hidden away from Big Brother. (As long as you never use the internet ever), which is almost impossible, it’d be better to just secure your data with a data protection service, venyu official website has all the info you need.
Linux is more reliable when compared to Windows. Linux will rock with its top-notch design, built-in security resulting un-parallel up-time. Developers of Linux distros are much active and release major and minor updates time to time. Traditionally Unix-like systems are known for running for years without a single failure or having a situation which demands a restart. This is an important factor especially choosing a server system. Definitely Linux being a UNIX-like system, it will be a better choice.
Linux systems are known for consuming fewer system resources (RAM, disk space etc.) when compared to Windows. Hardware vendors already realized the popularity of Linux and started making Linux compliant hardware/drivers. When running the OS on older hardware, Windows is slower.
Linux distros like Lubuntu, Knoppix, LXLE, antiX, Puppy Linux are best suitable for aging machines. Old horses like 386 or 486 machines with decent RAM (>= 124/256) can run Linux.
Linux can be installed and used it as a desktop, firewall, a file server, or a web server. Linux allows a user to control every aspect of the operating systems. As Linux is an open-source operating system, it allows a user to modify its source (even source code of applications) itself as per the user requirements. Linux allows the user to install only the desired software nothing else (no bloatware). Linux allows full freedom to install open source applications its vast repository. Windows will bore you with its default desktop theme whereas with Linux you can choose from many desktop themes available.
You can breathe fresh air after choosing a Linux distro from an available list of Linux distros.

Red Hat Enterprise Linux 8 (RHEL 8) is now available on all eRacks Systems with lots of developer-friendly capabilities.
Red Hat Inc. announced the official release of Red Hat Enterprise Linux (RHEL) 8 on May 7, 2019.
Red Hat Enterprise Linux 8 (RHEL 8) comes with new features and improvements as compared to the predecessor – RHEL 7. Some of the new features of RHEL 8 are as described below.
Kernel & OS
Red Hat Enterprise Linux 8.0 is based on Fedora 28 and upstream kernel 4.18. This provides users with a secure, stable and consistent foundation across hybrid cloud and Data Center deployments with tools needed to support all levels of workloads.
Storage and File systems
Stratis is the new local storage manager for RHEL 8. It provides managed file systems on top of pools of storage with additional features to the user. Stratis provides ZFS/Btrfs-style features by integrating layers Linux’s device mapper subsystem, and the XFS filesystem.
Stratis supports LUKSv2 disk encryption and Network-Bound Disk Encryption (NBDE) for more robust data security that can also be used for email security SaaS also, since there is threat of data loss in every digital medium as the technology progresses to a new level everyday. The OT cybersecurity solutions is the one companies are opting for these days to protect data.
- With Stratis, you can easily perform storage tasks such as:
- Maintain file systems
- Manage snapshots and thin provisioning
- Automatically grow file system sizes as needed
Pools are created from one or more storage devices, and volumes are created from a pool. The file system is created on top of a volume, hence resizing a volume automatically resize FS as well. The default file system used by Stratis is XFS.
Other notable Storage features are:
- The XFS file system now supports shared copy-on-write data extent functionality. This enables two or more files to share a common set of data blocks. Creating shared copies does not utilize disk I/O nor consume additional disk space. The files sharing common blocks act like regular files.
- The shared copy-on-write data extents are now enabled by default when creating an XFS file system, starting with the xfsprogs package version 4.17.0-2.el8.
- Support for Virtual Data Optimizer (VDO) on all of the architectures supported by RHEL 8.
- LUKS2 is now the default format for encrypting volumes. This replaces the legacy LUKS (LUKS1) format distributed in RHEL 7. LUKS2 provides encrypted volumes with metadata auto-recovery and redundancy if partial metadata corruption is encountered.
- Red Hat Enterprise Linux 8 is distributed with qemu-kvm 2.12 with – Q35 guest machine type support, UEFI guest boot support, vCPU hot plug and hot unplug, NUMA tuning and pinning in the guest and guest I/O threading
- The QEMU emulator introduces the sandboxing feature. QEMU sandboxing provides configurable limitations to what systems calls QEMU can perform, and thus makes virtual machines more secure
- KVM virtualization now supports the User-Mode Instruction Prevention (UMIP) feature, which can help prevent user-space applications from accessing to system-wide settings
- KVM virtualization now supports the 5-level paging feature, which significantly increases the physical and virtual address space that the host and guest systems can use.
- NVIDIA vGPU is now compatible with the VNC console
- Ceph storage is supported by KVM virtualization on all CPU architectures supported by Red Hat
- Q35, a more modern PCI Express-based machine type is supported by RHEL 8 Virtualization. All virtual machines created in RHEL 8 are set to use Q35 PC machine type by default
Below are the new changes in the Networking Level:
- RHEL 8 is distributed with TCP networking stack version 4.16, which provides higher performances, better scalability, and more stability.
- The networking stack upgraded to upstream version 4.18
- Iptables has been replaced by the nftablesframework as the default network packet filtering facility.
- The nftables framework is the designated successor to the iptables, ip6tables, arptables, and ebtables tools. This provides a single framework for both the IPv4 and IPv6 protocols
- The firewalld daemon now uses nftables as its default backend.
- Support for IPVLAN virtual network drivers that enable the network connectivity for multiple containers.
- Network Manager now supports single-root I/O virtualization (SR-IOV) virtual functions (VF). Network Manager allows configuring some attributes of the VFs, such as the MAC address, VLAN, the spoof checking the setting and allowed bitrate
Red Hat Enterprise Linux 8 has two modes of Content distribution and will only need two repositories enabled.
- BaseOS repository – The BaseOS repository provides the underlying core OS content in the form of traditional RPM packages. BaseOS components have a life cycle identical to that of content in previous Red Hat Enterprise Linux releases.
- AppStream repository – The Application Stream repository provides all the applications you might want to run in a given userspace. Other software that has special licensing are available on a Supplemental repository.
Web servers, Web Tools, Web Management – Cockpit, Compilers, Languages & Databases, Software Management
Red Hat Enterprise Linux 8 includes Application Streams of multiple versions of databases, languages, compilers, and other tools available for your use.
RHEL 8 comes with Cockpit automatically installed and firewall ports required by Cockpit are automatically opened. Cockpit interface can be used to apply Policy-Based Decryption (PBD) rules to disks on managed systems.
RHEL 8 YUM package manager is now based on the DNF technology and it provides support for modular content, increased performance, and a well-designed stable API for integration with tooling. The version of RPM is 4.14.2 and it validates the whole package contents before it starts the installation.
RHEL default Desktop Environment is GNOME. The GNOME Project is supported by the GNOME Foundation. Gnome version 3.28 shipped in RHEL 8 which has automatic downloading of operating systems in Boxes. Other new features include:
- New on-screen keyboard
- New GNOME Boxes features
- Extended devices support, most significantly integration for the Thunderbolt 3 interface
- Improvements for GNOME Software, dconf-editor and GNOME Terminal
- GNOME Software utility, which enables you to install and update applications and gnome-shell extensions.
- GNOME Display Manager (GDM) use Wayland as their default display server instead of the X.org server
Features of Wayland display server
- Stronger security model
- Improved multi-monitor handling
- Improved user interface (UI) scaling
- The desktop can control window handling directly.
RHEL 8 comes with support for OpenSSL 1.1.1 and TLS 1.3. This enables you to secure customer’s data with the latest standards for cryptographic protection.
RHEL 8 comes with System-wide Cryptographic Policies which helps you with the management of cryptographic compliance. No need to modify and tune specific applications.
OpenSSH has been rebased to version 7.8p1– with no support for SSH version 1 protocol, Blowfish/CAST/RC4 ciphers, hmac-ripemd160 message authentication code.
Red Hat Developer Subscriptions
Red Hat Developer members have been enjoying no-cost developer subscriptions for 3+ years now, and RHEL 8 is now automatically part of that. If your company wants developer support, there are several Red Hat Enterprise Linux Developer Subscriptions options with Red Hat support, too.
For more detail please contact eRacks Systems or visit Red Hat Enterprise Linux 8 official Page.

Fedora 30 is now available on all eRacks systems.
Fedora is a community-driven Linux distro that’s sponsored by the open source giant Red Hat. As Fedora is the upstream source of the company’s commercial RHEL distro, it’s also used as a testing ground for RHEL. As Linux enthusiasts might already know, Fedora is known as an innovative Linux distro that doesn’t hesitate when it comes to testing new technologies and helping other distros by making changes upstream for all distros. Shipping with many useful open source software, it’s known for providing a GNOME-based fluid desktop experience.
Fedora community recently released Fedora 30 just after about the 6 months from the version release as Fedora 29. On Fedora magazine they wrote about the early release of Fedora 30.
“It seems like it was just six months ago that we announced Fedora 29, and here we are again. Today, we announce our next operating system release. Even though it went so quickly, a lot has happened in the last half year, and you’ll see the results in Fedora 30.”
Many desktop users love Red Hat’s community Linux Fedora. They have good reason. Fedora is a great Linux desktop. But Fedora’s far more than just a desktop. It comes in three major versions: One for the workstation, another for containers, and still another that works as a server both on your server hardware and on the cloud.
About many changes, “Matthew Miller”, the Fedora Project Leader, explained in a statement:
“Computing scenarios don’t remain static and neither does Fedora. With the updates around Fedora 30, we’re providing an evolving spectrum of operating system editions to better meet diverse IT challenges. From containerized developer workspaces with Flatpak and Silverblue to expanded server and container infrastructure options in Fedora 30 Cloud and Fedora CoreOS, the Fedora Project remains focused on Linux innovation.“
New features in Fedora 30
The biggest change in Fedora 30 is the new GNOME 3.32 desktop environment. Over the course of past few releases, GNOME desktop has made many changes to reduce its memory consumption; GNOME 3.32 takes things further and makes things more fluid and snappier by making enhancements in the core GNOME libraries.
On the visual front, the desktop environment adds a refreshed visual style that makes the overall look more polished. Moreover, the application icons, user icons, buttons, switches, etc., are also redesigned.
Talking about different packages that are included in the distro, you get the latest GCC 9, PHP 7.3, Bash 5.0, Ruby 2.6, and other apps.
This release is powered by the latest Linux 5.0, which brings better hardware support and display performance. You also get new features like support for energy-aware scheduling, Btrfs swap file, AMDGPU FreeSync, etc.
With the Fedora 30 release, the cloud and server releases are being combined into the Fedora Server Edition. Also, Fedora CoreOS is replacing Fedora Atomic Host as the container-focused offering. There are other variants as well, including Fedora Spins and Labs.
Fedora 30 Workstation
Fedora 30 Workstation includes the latest version of the GNOME interface, GNOME 3.32. Fedora also supports the other major Linux desktop environments, including Cinnamon, KDE, LXDE, MATE, and Xfce. It also includes fractional scaling, a refreshed visual style, animation improvements, and new icons. The net effect is to make a more visually pleasing desktop, which works well on high-end monitors.
Fedora Workstation now uses the “flicker-free boot” system, so the display does not turn on and off during the boot process.
You can also now run the Fedora desktop as a containerized desktop, Fedora Silverblue, with rpm-ostree at its heart. This replaces the traditional RPM package management with atomic upgrade/rollback. In this model, Fedora provides ready-made base operating system image. When you install a program, using either rpm-ostree or Flatpak, it creates essentially a restore point. These are then tracked, and if something goes wrong, you can reset to your restore point with minimal harm done.
Fedora 30 Server
Fedora 30, released April 30, 2019, has the following new and improved features:
The product definitions for Fedora’s “Editions” have been revamped. Fedora Cloud and Fedora Server editions are now a single product, simply called Fedora Server. Fedora Atomic Host has been replaced with Fedora CoreOS, in the wake of Red Hat’s acquisition of that container-based Linux distribution. Fedora Workstation remains mostly the same.
Fedora Server now supports Linux System Roles, created by Ansible to provide consistent ways to configure common Linux subsystems such as the network, the email system (Postfix), SELinux, and a few others. The list of roles is constantly being expanded.
Almost all Python 2 packages have been removed from the system, as part of Fedora’s switch from Python 2 to Python 3.
MongoDB has been removed from Fedora, as its licensing (the Server-Side Public License v1) is not believed to be compatible with other free software licenses.
Support for many deprecated cryptography standards is being removed: DES, 3DES, CRC32, and MD4. RC4 and MD5 are being marked as deprecated.
As with each edition of Fedora, many individual software components have been upgraded:
- Bash 5.0
- Boost 1.69
- Erlang 21
- FreeIPA 4.8 (which now uses Python 3.6)
- GCC 9
- glibc 2.29
- Golang 1.12
- GNOME 3.32
- Haskell GHC 8.4
- java-openjdk JDK12
- PHP 7.3
- Ruby 2.6
- Vagrant 2.2
For more details please visit the official Fedora Releases/30/ChangeSet.
To upgrade your existing Fedora 29 installation to Fedora 30, you need to run the following commands in terminal one by one:
sudo dnf upgrade --refresh
sudo dnf install dnf-plugin-system-upgrade
sudo dnf install dnf-plugin-system-upgrade
sudo dnf system-upgrade reboot
You can also perform a clean installation of the Fedora 30 by visiting its download page and download the ISO file. Or click the link below:
If you feel like doing so, do give it a try or ask for the help from eRacks Systems’ experts.

Ubuntu 18.04 LTS (Bionic Beaver) has been released on 26th April 2018 following its planned release schedule. Canonical named this Long Term Support version with codename “Bionic Beaver”, where ‘Bionic‘ is an adjective meaning to have or use an artificial, typically electromechanical, body part. And a ‘Beaver‘ is large nocturnal rodent able to swim in water. Beavers are famous for building dams, canals, and homes along river banks.
Ubuntu 18.04 LTS (Bionic Beaver)
On 26 January 2018, Will Cooke (Desktop Engineering Manager) wrote in an Ubuntu’s Blog post about Ubuntu 18.04 LTS (Bionic Beaver) as, “Bionic Beaver, the codename for the next Ubuntu LTS release, is due in April 2018 and will ship with both the traditional Xorg graphics stack as well as the newer Wayland based stack, but Xorg will be the default.”
Ubuntu 18.04 LTS (Bionic Beaver) Support lifespan
Ubuntu 18.04 is an LTS version, which means that the ‘main’ archive of Ubuntu 18.04 LTS will be supported for 5 years until April 2023 from its release date April 2018. Ubuntu 18.04 LTS will be supported for 5 years for Ubuntu Desktop, Ubuntu Server, and Ubuntu Core. Ubuntu Studio 18.04 will be supported for 9 months. All other flavors will be supported for 3 years.
Compared with the previous Ubuntu LTS edition (Ubuntu 16.04.4 LTS Xenial Xerus), there are a lot of changes in the new Ubuntu LTS release (Ubuntu 18.04 LTS Bionic Beaver).
Let’s see what’s new in Ubuntu 18.04 LTS Bionic Beaver release:
What’s new in Ubuntu 18.04 LTS (Bionic Beaver)
Xorg will be used by default instead of Wayland
Ubuntu 17.10 used the Wayland graphics server by default. With Ubuntu 18.04, the default graphics server will change to Xorg. Wayland will still be available as an option, but Xorg will be the default, out-of-the-box one. The Ubuntu Desktop team decided to go with Xorg for its compatibility with services like Skype, Google Hangouts, WebRTC services, VNC and RDP, and more.
Xorg with Ubuntu 18.04 LTS
Ubuntu 18.04 minimal install option
Ubuntu 18.04 will use Ubiquity, the Ubuntu installer you’re probably already familiar with. Though the developers plan on implementing Subiquity, 18.04 will use Ubiquity, which will have a new “minimal install” option that you can choose during setup. Minimal install basically means the same Ubuntu, but without most of the pre-installed software. The minimal install option saves about 500 MB, and is only 28MB in size when it is compressed.
CPU usage improvements and bug fixes
The most notable improvement will be in CPU usage. The Ubuntu Desktop team has greatly improved and reduced the CPU usage caused by Ubuntu 18.04. They’ve also fixed hundreds of bugs and made hundreds of other small improvements.
Software, updates and other tweaks
If you missed the Ubuntu Welcome tool you can still enable LivePatch via Software & Updates. Open Activities and search for Software & Updates.
Software & Updates.
From the Updates tab you can enable and disable Live Patch:
Enable/ Disable Live Patch
There are some other useful settings in GNOME Control Center which you might like to toggle:
GNOME Control Center
By enabling Location Services your clock can automatically switch to the correct time zone for where you are which is useful for frequent travelers. By enabling automatic error reporting crash reports will be automatically generated and uploaded. By collecting these error reports, Canonical can easily spot trends in common problems and make sure they work on getting the most common bugs fixed first.
Ubuntu 18.04 Desktop will have a new theme
Ubuntu 18.04 will ship with Ambience and it won’t use a new theme by default. The new Communitheme won’t even be installed. The Desktop team has decided to do this for various reasons, including bugs and lack of testing.
Luckily, you can still use the Communitheme, but you’ll have to install it yourself. The Communitheme can be installed easily via a snap, but you can always install it manually.
New Communitheme with Ubuntu 18.04 LTS
GNOME Desktop Environment
Ubuntu started using the GNOME desktop environment with Ubuntu 17.10 instead of the default Unity environment. Ubuntu 18.04 will continue using GNOME. This is not a major change to Ubuntu, but GNOME has also done a lot of changes to their desktop environment, as well as new features. An improved dock, an on-screen keyboard, and more.
GNOME Desktop Environment
Ubuntu 18.04 Desktop will have a new app pre-installed
The new LTS desktop release will ship with a new app pre-installed by default. The app is GNOME To Do and it’s a very useful app for organizing lists, tasks, and more. You can prioritize them. color them, set due dates, and a number of other features.
GNOME To Do
Applications will be installed as snaps by default
They been planning on using snaps for a while, and they finally shipped GNOME Calculator as a snap instead of a deb. This is a test to help the Desktop team find and fix any bugs. They’ll later on move more applications to snap in the final release. Using snaps will make the process of installing and updating apps much easier. You can even install snaps on any distro and device.
Some New Apps
Some New Apps
New snaps are being added to the store all the time, and you can already download essentials like Spotify, Skype and Slack. You can browse the full range of applications via GNOME Software (click the Open “Software” now button) or access the highlights directly by clicking on their icon.
A Brand New Icon Set
A Brand New Icon Set
Open source icon project Suru has been incorporated into Ubuntu 18.04. These icons were originally seen in the abandoned Ubuntu Touch mobile operating system. Despite hopes to the contrary and a dedicated community project, Ubuntu 18.04 will not boast a fresh new look. However, while the Ambiance theme is hanging around, new icons are expected in Ubuntu.
Some tweaks will give you color emojis on versions of Ubuntu prior to 18.04 LTS, this is the first time they’ve been included by default. The emojis you’ll find in Ubuntu 18.04 LTS are the same open source emojis as found on Android. For many users, these will be familiar.
Ubuntu 18.04 will collect data about your system and make it public
Ubuntu 18.04 will collect data like the Ubuntu flavor you’re using, hardware stats, your country etc. Anyone can opt-out of this, but it’s enabled by default. What’s interesting about this is that the data they collect will be public, and no sensitive data will be collected. so most of the Ubuntu community supports this decision.
However, there is a potential security concern that you should be aware of. With Ubuntu 18.04 LTS, Canonical intends to collect data from your computer. Though there is nothing personally identifiable in this data. Instead, it is to establish your computer’s hardware components, what version of Ubuntu you’re running, your location (based on your choice when setting up Ubuntu) and a few other things.
Collecting data about your system
This marks a change from Canonical’s previous attitude to this sort of data collection, but is understandable given how flakey figures are for Linux usage around the world. Crucially, this data collection can be opted out of; if you’re upgrading from a previous version of Ubuntu, meanwhile, you can also opt in.
Alongside these changes Canonical has made some noticeable upgrade on packages for Ubuntu 18.04 Bionic Beaver too. Some of them are as follows,
Linux kernel 4.15
Ubuntu 18.04 ships with a v4.15 based Linux kernel, enabling the latest hardware and peripherals available. The 18.04 kernel delivers new features inherited from upstream, including:
- CPU controller for the cgroup v2 interface.
- AMD secure memory encryption support.
- The latest MD driver with software RAID enhancements.
- Improved power management for systems with SATA Link Power Management.
- Linux security module stacking support.
- Support for signing of POWER host and NV kernels.
As of 18.04 release, OpenJDK 10 is the default JRE/JDK. Once OpenJDK 11 reaches GA in September 2018, it will become the default in 18.04.
OpenJDK 8 has moved to universe and will remain available there for the life of 18.04, to provide migration time for packages, custom applications, or scripts that can’t be built with OpenJDK 10 or 11. OpenJDK 8 will be updated in 18.04 after Ubuntu 16.04 LTS reaches EOL in April 2021.
In Ubuntu 18.04 LTS, gcc is now set by default to compile applications as position independent executables (PIE) as well as with immediate binding, to make more effective use of Address Space Layout Randomization (ASLR). All packages in main have been rebuilt to take advantage of this, with a few exceptions. Also, bolt and thunderbolt-tools have been promoted to main to provide security controls for Thunderbolt devices.
Default CIFS/SMB protocol version change in CIFS mounts
Since 17.10, the default SMB protocol used when mounting remote CIFS file systems via “mount.cifs” is changed to 2.1 or higher, depending on what is negotiated with the server.
At a glance change in Ubuntu 18.04 LTS (Bionic Beaver) Desktop Edition
- Wayland is provided as a Technical Preview and is expected to be the default display server in 20.04 LTS. To try it out, just choose Ubuntu on Wayland from the cog on the log in screen.
- The installer offers a minimal install option for a basic desktop environment with a web browser and core system utilities. Many official 18.04 desktop flavors are using this new feature too!
- Apps provided by GNOME have been updated to 3.28.
- LibreOffice has been updated to 6.0.
- Emoji now show in color in most apps. Keyboard shortcuts for the emoji input chooser are Ctrl+. or Ctrl+;
- Calendar now supports weather forecasts.
- Some utilities have been switched to the snap format for new installs. Snap apps provide better isolation which allows them to be upgraded to new stable releases during the LTS lifecycle.
- The Characters app replaces the older Character Map by default.
- The Ubuntu Software app allows easy switching between different channels for Snap apps.
- The ‘To Do’ app has been added to the default normal install.
- spice-vdagent is pre-installed for better performance for spice clients such as the GNOME Boxes app.
- The right-click method for touchpads without physical buttons has changed to a two-finger click instead of clicking in the bottom right of the touchpad.
- Although libinput is the default driver for mice and touchpads, it is now possible to use the synaptics driver with the Settings App. Support for the synaptics driver will be dropped in a future Ubuntu release.
- Computers will automatically suspend after 20 minutes of inactivity while on battery power.
- GNOME Shell now supports Thunderbolt 3.
Comparing with Ubuntu 17.10 (Artful Aardvark) & Ubuntu 16.04.4 LTS (Xenial Xerus) the latest Ubuntu 18.04 Bionic Beaver Server edition’s packages are upgraded as well. Some of them are as follows,
The next generation Subiquity server installer, brings the comfortable live session and speedy install of Ubuntu Desktop to server users at last.
Ubuntu 18.04 Bionic Beaver Server Edition Installer
ifupdown has been deprecated in favor of netplan.io and is no longer present on new installs. Backend configuration on Ubuntu Server by default is provided by systemd-networkd.
LXD is the system container manager that ships with all Ubuntu servers. Ubuntu 18.04 includes the all new LXD 3.0 release, some of the highlights include:
- Clustering of LXD servers (one big virtual LXD)
- Support for NVIDIA runtime pass-through
- Remote transfer of custom storage volumes
- Extended /dev/lxd API inside the containers
- Support for port redirection
- Numerous improvements to the command line tools
A new external tool called lxd-p2c is also available to turn existing systems into LXD containers.
QEMU has been updated to the 2.11.1 release.
Among many other changes, fixes around Meltdown/Spectre are included. Since fully utilizing these mitigations needs more than just an upgrade, it is recommended to read details at the qemu.org blog post.
QEMU in Ubuntu 18.04 now has rdma support enabled as over the past year much unification in the rdma-core project has occurred.
Migrations from former versions are supported just as usual. When upgrading it is always recommended to upgrade the machine types allowing guests to fully benefit from all the improvements and fixes of the most recent version.
libvirt has been updated to version 4.0.
The packaging now builds libvirt storage drivers as pluggable libraries. This slims down the installation requirements but some drivers of less general interest will now be found in universe. On the other hand, that means that a few formerly integrated features like rbd or zfs now might require you to install the package after upgrade.
Ubuntu includes 17.11.x the latest stable release branch of DPDK.
By the new Stable Release exception for DPDK future stable updates to 17.11.x will be made available to Ubuntu 18.04 LTS.
Open vSwitch 2.9
Open vSwitch has been updated to 2.9.
- NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
- Ovs-vsctl and other commands that display data in tables now support amax-column-width option to limit column width.
- Added support to send IPv6 Router Advertisement packets in response to the IPv6 Router Solicitation packets from the VIF ports.
- No longer send packets to the Linux TAP device if it’s DOWN unless it is in another networking namespace.
In Ubuntu 18.04 LTS chrony will replace ntpd as the recommended server for the NTP protocol. The comparison among ntp servers by the chrony maintainers may interest some users looking to see a high-level reason why this change was made. It does lack the rather new and not yet completely ready ntpsec, but otherwise is a fair analysis.
For simple time sync needs the base system already comes with systemd-timesyncd. Chrony is only needed to act as a time server or if you want the advertised more accurate and efficient syncing.
Going along with this change, ntpd has been demoted from main to universe. ntpd will continue to work but will only receive best-effort security maintenance. When upgrading to Ubuntu 18.04 LTS it is highly recommended to migrate to chrony if you had set up ntpd before.
The version was updated to 18.2. Notable new features include:
- VMware: support for 64-bit platforms and identifying OVF data source provided.
- GCE: Improvements and changes to ssh key behavior for default user.
- Azure pre-provisioning speed improvements.
- NoCloudKVM and EC2 tests now run in continuous integration.
- New cloud support: IBMCloud and HetznerCloud now have official data sources and OpenTelekom is now recognized by cloud-id.
- OpenNebula: Improve network configuration support.
- New cloud-init command-line tools available: status, analyze and clean.
- New ubuntu cloud-config modules for managing snaps and ubuntu-advantage services.
The version was updated to 18.1. Notable features include:
- Add experimental zpool and zfs filesystem support, including ZFS on root.
- Add support for installing remote sources that are a filesystem image.
- Add pollinate user-agent configuration support.
- Improved device teardown of dirty devices to support re-deployment.
- Default config now automatically tars curtin logs upon error using new curtin collect-logs command.
- storage: accept filesystem mount options.
- Extensive integration test coverage and improvements.
The version was updated to 2.4b2. Notable features include:
- Add audit logging.
- Add KVM pod support to create tags, select the storage pool, and compose machines with multiple storage pools.
- Add UI for DNS management.
- Add the commissioning template framework for HBA management.
- Add the commissioning template framework for Firmware Upgrades.
- Improve UI performance by performance.
- Improve MAAS’ backend performance.
- Improve the UI for the Settings.
