Ubuntu 26.04 LTS Resolute Raccoon enters the Beta freeze!

As we are approaching the beta stage of Ubuntu 26.04 LTS Resolute Raccoon, the version has finally entered the Beta Freeze as of today on March 23rd, which is a stage that all further package releases that affect the beta release after the freeze date will have to undergo manual approval by the release team before entering the archives.

Before the beta freeze, all uploads can enter the archive without any human intervention, which supports fast development during the early stages of a Ubuntu version development. After the freeze, manual approval for essential packages is required to ensure that the beta release stays stable by fixing package inconsistencies and critical bugs quickly.

After the freeze, all packages that don’t affect the beta release will still be automatically approved without any human intervention until the final freeze, scheduled for April 16th.

Ubuntu 26.04 LTS Resolute Raccon Beta will be released on March 26th, which will allow users to conduct tests on an upcoming version of Ubuntu before the official release on April 23rd.

Ubuntu 26.04 LTS Resolute Raccoon enters the User Interface freeze

Today, Ubuntu 26.04 LTS Resolute Raccoon has entered a new stage of development, according to the release schedule.

The official Ubuntu documentation states that the user interface freeze means that there will be no more changes to how the upcoming version of Ubuntu looks, alongside the user interface elements and appearance. This has the following advantages for those working on the project:

• Documentation writers and translators will be able to work on a fixed target without the user interface changes causing chaos for them.
• Screenshot and documentations don’t become obsolete caused by a change in the user interface.

By preventing obsoletion of both the docs and the screenshots, this makes sure that users who need help using a specific application get the most up-to-date instructions.

To explain the freeze in more depth, here’s when will the changes be considered unacceptable:

• User Interface of individual applications that are installed by default
• Appearance of the Desktop
• Distribution-specific artwork
• All user-visible strings in the Desktop and applications that are installed by default

However, an exception can be applied in certain circumstances, and can be filed using the official bug tracker at Launchpad. These bugs explain the justification for the UI change, as well as the explanation as to how its benefits would break existing documentation, screenshots, and translations. You can request for the UI freeze exception here.

Ubuntu 26.04 LTS Resolute Raccoon will be released on April 23rd.

Ubuntu 26.04 LTS Resolute Raccoon Snapshot 4 released!

The fourth and the last snapshot has been released, highlighting the changes between the previous snapshot (January 29th) and the current one (February 26th). On March 26th, Ubuntu 25.10 Questing Quokka will reach the Beta stage according to the planned release schedule.

The official plan stated that the Ubuntu release team wanted to release Ubuntu every six months, while relying on the modern software engineering practices. More automated testing will be made to ensure that future releases will have next-to-zero problems that may cause a delay of the release. Alongside this, the release process will be refined to achieve the goal of little to no human intervention when dealing with releases.

The Ubuntu release team describe the snapshot releases as not production-ready releases, but as testable milestones that allow you to try out the upcoming version of Ubuntu without having to wait until the official release.

You can find those snapshots here:

• Ubuntu
• Edubuntu
• Kubuntu
• Lubuntu
• Xubuntu
• Ubuntu Budgie
• Ubuntu MATE
• Ubuntu Unity
• Ubuntu Cinnamon
• Ubuntu Kylin (麒麟)
• Ubuntu Studio

Why not try out this snapshot to get early access to new features and to report bugs?

Ubuntu 26.04 LTS Resolute Raccoon official wallpapers revealed!

Prior to the release of Ubuntu 26.04 LTS Resolute Raccoon Beta, the Ubuntu artwork team have finally revealed the official wallpapers for this version of Ubuntu that is scheduled for April 2026. Before, we just have a mascot name for the release.

Now, the official wallpapers are here, since this version of Ubuntu is a little more than two months away from the release. Meanwhile, the wallpaper competition vote is still running until February 20th, and you can vote for the wallpaper here.

See the official wallpapers, which will make it to the final version of Ubuntu 26.04, below:

Ubuntu 26.04 LTS Resolute Raccoon Snapshot 3 will get GNOME 50 Beta

The upcoming Ubuntu 26.04 LTS Resolute Raccoon’s third snapshot, which will be released on January 29th, will get the beta version of GNOME 50. It’s known that the stable release of this version of Ubuntu provides the stable version of GNOME 50, but the beta version will make it to the third snapshot of the upcoming release.

Just to remind you that Ubuntu snapshots have been first implemented in Questing Quokka in an attempt to streamline the development workflow and to gives curious users early access to what will the upcoming version of Ubuntu look like, with the first ever snapshot being made released on May 29th of the last year. This will make sure that automation is used to make future Ubuntu releases, such as this release, more stable.

GNOME 50 is currently in development with the Alpha version stripping out support for the legacy X11 desktop protocol as Wayland becomes more stable. Although there are still compatibility issues with applications that use the legacy X11 protocol in a way that Wayland hasn’t solved yet, such as remote access programs, Wayland is getting better. GNOME 50 will be released on March 18th, 2026.

However, the beta version of GNOME 50 will include more stability improvements and bug fixes as we venture into both the release candidate and the final release of this desktop environment. This way, Ubuntu 26.04 LTS will use GNOME 50 as the desktop environment in the final release.

Ubuntu’s Resolute Raccoon 26.04 LTS roadmap!

Ubuntu has published the Ubuntu 26.04 Resolute Raccoon roadmap for the next LTS version last November, and the list of changes that will be made to this Ubuntu version is rather surprising. Those changes have been listed in the official Discourse forums since the start of the development, and we’re now at the stage where the beta version is only a month and a few days left. Full development is still ongoing, with the list of expected changes below:

• GNOME 50 will make it to the final release of Ubuntu 26.04, which is expected to be released on April 23rd, 2026. Showtime and Resources will become the new default applications in all desktop installations.
• As for Wayland on NVIDIA GPUs, including the latest GeForce RTX 50-series graphics cards released last year, outstanding stability and performance issues will be fixed in this release so users with those graphics cards can now have even better experience. Wayland will become the default starting 26.04.
• The fingerprint reader support has now become more powerful, because Ubuntu 26.04 LTS delivers secure, SPDM-based fingerprint authentication, which brings more reliability to the biometrics system in certified Ubuntu devices.
• As for the built-in software sandboxing solution, Snap, its integration with the desktop has now become much better than before. Snaps will play nicer with the Ubuntu desktop, by improving app recognition and by making launchers behave more predictably.

Alongside that, there have been plans to make accessibility more visible, and the Ubuntu’s goal is to make the whole operating system accessible to all users from the very start. In enterprise environments, enhanced cloud authentication has been achieved using a first-party authentication daemon called authd. This will make enterprise authentication with different services easier and smoother, ensuring cohesive authentication across enterprise developments.

Ubuntu 26.04 LTS also enhances the developer experience on Windows by introducing a better experience with consistent and predictable workflow in the latest WSL images. Ubuntu Pro is also supported, with the necessary polishes being made to provide post-release support. Documentation will also go through a huge rework to fend off old docs and add new ones, to keep the user documentation in par with the latest Ubuntu releases.

The release milestones are as follows:

• Feature Freeze: February 16th, 2026
• User Interface Freeze: March 12th, 2026
• Beta Release: March 23rd, 2026
• Final Freeze: April 16th, 2026
• Final Release: April 23rd, 2026

.NET 8.0 LTS is not installable on Ubuntu 26.04 LTS Resolute Raccoon

During development of Ubuntu 26.04 LTS Resolute Raccoon, which is expected to come with .NET 10.0 LTS that was released last week, there was a proposal to remove .NET 8.0 from the list of installable software in both the runtime and the SDK forms. This was made in accordance with the comment in a 2023 .NET 6.0 bug that stated:

As .NET 10.0 is a long-term release that will make its way to Ubuntu 26.04 Resolute Raccoon, it has been backported to Ubuntu 24.04 LTS, which is the current LTS version that is supported as of the time of writing. Meanwhile, .NET 8.0 has already been backported to Ubuntu 22.04 LTS Jammy Jellyfish, and there is no mention of forward-porting the version to the next Ubuntu LTS version.

To satisfy this condition, all packages that are related to .NET 8.0 have been removed from Ubuntu 26.04 LTS Resolute Raccoon. You can take a look at this bug’s logs here.

Starting from today, you’ll no longer be able to install .NET 8.0 from your development system from official Ubuntu repositories if you’re running the development branch of Resolute Raccoon. You’ll either have to upgrade your applications to .NET 10.0, or you’ll have to manually install .NET 8.0.

Meanwhile, the team is running into issues with packaging the final version of .NET 10.0 for the same version of Ubuntu, but those issues should be fixed soon so that developers can finally have access to the latest .NET version.

As a consequence, we had to remove all Nitrocid and BassBoom packages for Ubuntu 26.04 LTS Resolute Raccoon until all packages that are related to .NET 10.0 have landed.

Ubuntu 26.04 LTS Resolute Raccoon release date is known

The release schedule for the Resolute Raccoon is now known to us as Ubuntu 25.10 Questing Quokka got released last week. The Ubuntu team is now working on Ubuntu 26.04 LTS Resolute Raccoon as development has just started. As we have mentioned earlier, the repositories have been initialized for the next LTS after Ubuntu 24.04 LTS Noble Numbat, and the daily builds will use those repositories to help shape the future of Ubuntu.

The release schedule is now known, and you can see the full schedule here. According to the schedule, we have seen interesting dates, especially when it comes to the most important milestones, such as the final release. So, we have two big milestones:

• Beta release: March 26th after the beta freeze on March 23rd
• Final release: April 23rd, a week after the release candidate

Ubuntu 26.04 LTS release schedule is not finalized yet, as development has just started, so delays could occur. Once released, it’s going to be the next version of Ubuntu for enterprise solutions to use.

Ubuntu 26.04 Resolute Raccoon will use .NET 10.0!

Ubuntu 26.04 LTS Resolute Raccoon is reportedly to start development in a week after the release of Ubuntu 25.10 Questing Quokka, which was released today. This version of Ubuntu will feature the upcoming .NET 10.0 LTS release which will be supported for up to three years, with the most interesting features being in the final release. With Ubuntu 26.04 LTS about to start development, .NET 10.0 would have been already updated to its second release candidate, a milestone before the final release.

Ubuntu 26.04 LTS is going to be the tenth long term support release, which is a very interesting milestone as we are heading towards years and years of improvements that happened to Ubuntu, starting from 2004 with the Warty Warthog. You can find out more about .NET 10.0 here.

.NET 10.0 is going to be the long-term support release for the modern .NET framework after 8.0, which was released on November 2023. Earlier, .NET 9.0 brought performance improvements, but .NET 10.0 will bring even more improvements across different areas of the framework.

Ubuntu 26.04 LTS will also update more frameworks and toolchains, including GCC, Python, and others, to support the latest features that will make it to the release. This will give developers new features to develop their applications, including the .NET ones, which .NET 10.0 provides.

.NET 10.0 brings improvements to the AOD applications, as well as the AVX10.2 support. It also brings C# 14, which introduces new features, such as unbound generic types support for the nameof expression.

Ubuntu 26.04 LTS Resolute Raccoon will be released on April 2026, while .NET 10.0 will go live on November 2025.
