Linux Mint 21.1 “Vera” was released on December 20, 2022, a full 14 days after the beta appeared. The popular Ubuntu-based distribution’s intuitive desktop environments make it especially popular among newcomers to Linux.
Linux Mint 21.1 code name “Vera”, brings several interface changes including a cleaner desktop with more vibrant colors. Vera also sees the arrival of more controls in the update, driver, and software managers. New system sounds, ISO tools, and mouse pointers round out this update to the popular Linux distribution.
Let’s see what new Linux Mint 21.1 has in its store for users.
Linux Mint is one of the most successful distributions based on Ubuntu. And with the number of Ubuntu derivatives out there, that’s saying something. Linux Mint must be doing a lot of things right—at least, according to its passionate user base.
Linux Mint is focused on desktops and laptops. It provides customized desktop environments with a choice of Cinnamon, Xfce, and Mate. It has the Snap store disabled by default; a move first made in Linux Mint 20.
Linux Mint doesn’t have a server version. Its purpose is to provide a simple, intuitive, attractive desktop Linux experience for its users, especially newcomers to the Linux world. The Linux Mint team want a mac or Windows user to be comfortable with Linux Mint within a short time.
The release will continue to use the Linux 5.15 LTS kernel under the hood, based on Ubuntu 22.04 LTS.
When you first boot into the desktop, you should quickly notice the new look of the cursor. It features the new Bibata theme by default.
The cursor icon theme inventory has new options like Yaru, Breeze, and GoogleDot along with the traditional DMZ theme.
Users will also find a unique set of app icon themes to choose from in addition to the traditional Mint-X, Mint-Y, and Mint-Legacy themes. This includes Papirus, Breeze, Numix, and Yaru.
Another interesting thing you may notice is the default accent color isn’t the traditional green anymore, and that’s because the desktop theme is now switched to Aqua. The accent color library offers more vibrant colors and gives the desktop a clean and attractive look.
For those who want the legacy look back, there exists a “Mint-Y-Legacy” option in the theme options.
Moreover, the Computer, Home, Networks, and Trash icons previously visible on the desktop are removed by default and can be accessed in the file manager. The Home folder icon is displayed on the panel instead. If you want to return the old arrangement, you can do so by heading to the system preferences.
The desktop has been purged. The “home”, “computer”, “trash”, and “network” icons have been removed.
Clicking the folder icon pinned to the panel opens your “home” directory in the Nemo file browser, so it is still only one click away. Counter-intuitively, its tooltip reads “Files”, but it gives you a fast way to get to Nemo and your “home” directory all in one.
The “computer”, “trash”, and “network” locations are available through the “Go” menu in Nemo or by searching in the start menu.
Files that you copy or save to “~/Desktop” still show up on the desktop, as do mounted devices.
There’s the usual selection of new background wallpapers. You’ve got access to the generic Linux Mint wallpapers, the backgrounds from the Linux Mint 21 Vanessa release, and the new Vera-specific backgrounds.
It’s a stunning collection of images by skilled photographers. Whoever curated these backgrounds did a great job too.
There’s a new “Show Desktop” button at the extreme right-hand end of the panel. It hides all open windows, clearing the desktop with a single mouse click.
It’s practically invisible, but it’s there. Point at it, and you’ll see its tooltip.
The default mouse pointer has changed. Linux Mint 21.1 uses “Bibata Modern Classic”, which has a gently rounded shape without a tail.
With all of these cosmetic tweaks, what looks good is subjective. If you don’t like the defaults, you can change them in a flash to something more agreeable to you.
The system sounds have been updated. As before, the volume can be adjusted, and individual sounds can be switched on and off if they’re too distracting.
The Driver Manager application has been changed to run in user mode. This means it’ll run without the need for a password.
It searches your computer for drivers that are installed and in use, then lists them. It’ll also identify missing drivers and offer to install them.
Our test machine didn’t require any additional drivers, but it’s nice to know that you’ve got a helping hand if your computer does need them.
A similar amount of assistance and hand-holding is available in the Update Manager. It makes what can become a complicated task very easy. You can select the packages that you want to update, and exclude those you’re not interested in at this time.
Significantly, support for updating flatpaks has been added.
If a flatpack is available for an application, the Software Manager let’s you choose between installing a DEB “System Package” or a flatpack.
It’s not the flashiest software store application, but it looks good and works well. You can find what you want quickly from a huge choice of software, and you get a choice of install types, too. I’ll take that over eye candy any day.
As you’d expect USB Image Writer tool lets you select an ISO image and the USB stick you want to write the image to. It also has a “Verify” button which lets you verify the authenticity of the ISO image before you burn it, which is convenient.
The USB Stick Formatter tool formats USB sticks for you. You can pick a USB stick, set its device name, and choose a file system. There are four file systems supported:
The code which lets you remove applications from the main menu was reviewed and password prompts were removed in situations where administrative permissions weren’t required.
Removing a Flatpak will no longer require a password to be entered. Same goes for simple shortcuts and local applications (i.e. applications which aren’t installed system-wide).
Synaptic and the Update Manager will now also ask pkexec to remember your password so you won’t have to enter it every single time if you perform multiple operations.
Following the upstream deprecation of apt-key, the Software Sources received changes to rework the way it handles PPA keys.
When a PPA is added its key is now only accepted for the PPA itself, not globally for all APT Sources.
Continuous integration for all Linux Mint projects moved from Circle CI to Github Actions. This gives the development team greater control over docker.
Documentation was written and added to the User Guide to cover the following topics:
Including these, there are lot of new features in this new release. Start using new Linux Mint 21.1 to get the full experiences.
To get the Linux Mint 21.1 on your system, simply upgrade the existing Linux Minx 20.x or do a clean install.
Upgrading to Linux Mint 21.1 is simple. Long-time users of the distro will be familiar with the steps needed to do so:
Once all updates are downloaded, unpacked, and installed it’s advised to restart the computer. A reboot ensures all changes take effect, and that the system comes back-up functioning as intended by Linux Mint’s developers.
As mentioned, Linux Mint 21.1 includes a number of visual changes and new artwork. Anyone who makes the upgrade but doesn’t like the new folder icons or aqua color accents can revert to Linux Mint’s older look using the Welcome app available in the applications menu.
Before upgrading or clean install, make sure your system meets the minimum requirements. The system requirements are as follows.
If your system doesn’t meet the minimum system requirements, or you need clean pre-installed new system, you can always get one from eRacks Systems store as pre-configured with Linux Mint 21.1.

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:
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.
Ubuntu 20.10 Desktop
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:
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.
Noteworthy changes Ubuntu 20.10 Server:
System Requirements for Ubuntu 20.04:
Note: Optionally, Internet access is helpful.
Download Ubuntu 20.10
You can download Ubuntu 20.10 for 64-bit computers using the link below:
As the Ubuntu 20.10 desktop image is 2.9GB in size do make sure you’re on a decent internet connection before you hit the download button!
When the download completes you need write the Ubuntu 20.10 ISO image to a USB stick using a tool like Etcher. Then pop the USB in an empty port, reboot your computer, and choose to boot from the USB.
You can also upgrade to Ubuntu 20.10 from an earlier version.

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.
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
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:
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:
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:
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.
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 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.
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.

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.
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:
Below are the new changes in the Networking Level:
Red Hat Enterprise Linux 8 has two modes of Content distribution and will only need two repositories enabled.
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:
Features of Wayland display server
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.

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.“
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 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, 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:
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 18.10 ‘Cosmic Cuttlefish’ supported with 9 months of security updates, bug fixes and select app upgrades. Users of it will be able to upgrade to Ubuntu 19.04 when it’s released in April, 2019.
When the release of a new version as Ubuntu 18.10 ‘Cosmic Cuttlefish’, the first question arrives in mind, “What are updated comparing with the current Ubuntu 18.04 LTS version?”
The most important update in ‘Cosmic Cuttlefish’ is, it has updated Linux Kernel. Ubuntu 18.10 has Linux Kernel 4.18. This Kernel version has some improvements for AMD and Nvidia GPU, USB Type-C and Thunderbolt, and performance optimizations in CPUfreq among several other features.
Another important thing is having faster installation and boot with new compression algorithms. Working with new compression algorithms like LZ4 and ztsd, ‘Cosmic Cuttlefish’ is supposed to have around 10% faster boot. The installation will be slightly faster as well. Which is definitely the good news for all Ubuntu users.
As always Ubuntu 18.10 will have this new GNOME version. Most of the visual and under the hood changes in GNOME 3.30 will be seen in Ubuntu 18.10 as well.
Taking cue from Fedora 28, Canonical is also working to improve battery life for laptops. Linux kernel has options to switch HDD controllers, USB controllers and other such devices to a low power state when not in use. This lowers the overall power consumption and thus improves the battery life.
Ubuntu 18.04 was supposed to have a new look with the community developed Community theme. This theme could not be completed in time for the 18.04 release. But Ubuntu 18.10 has it. The ‘Cosmic Cuttlefish’ has the Yaru Community theme installed by default, giving it a ravishing fresh look.
Some other changes in the Ubuntu 18.10 ‘Cosmic Cuttlefish’ are as follows:
Ubuntu 18.10 ‘Cosmic Cuttlefish’ is a modest update compared to 18.04. The vast majority of notable improvements are tucked away out of sight, ‘under the hood’. Ubuntu 18.10 feels faster than 18.04, But you can’t “see” the changes that shape Ubuntu 18.10 ‘Cosmic Cuttlefish’, you almost certainly will feel them.
