Latest Ubuntu 20.10 “Groovy Gorilla” is Now Available!
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.
Security Improvements
- 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.
GNOME 3.38
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.
Updated Applications:
- Firefox version 81
- LibreOffice version 7.0.2
- Thunderbird version 78.3.2
Updated Subsystems:
- 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:

What’s new in Ubuntu 20.04 LTS “Focal Fossa”!
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).
focalfossa
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
Installer
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).
Installer
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.
Linux Kernel
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.
GNOME 3.36
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.
Network configuration
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.
ZFS support
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.
Snap Store
The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.
QEMU
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
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
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!

Red Hat Enterprise Linux 8 (RHEL 8) is now available on all eRacks Systems.
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.
Virtualization
- 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
Networking
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
Content Distribution
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.
Desktop Environment
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.
Security
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.

Fedora 30 is now available
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.“
Get your Own eRacks/FLASH10 Server Pre-configured with With Fedora 30 Server or Workstation Edition.
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
