Ubuntu Team announced the second development release of Ubuntu 26.04, Resolute Snapshot 2, yesterday afternoon (UTC time).
The date was moved up by a week, because of end-of-year (EOY) shutdown and the developers need more time to fix issues before holidays.
Whilst the snapshot was planned for next week, we wanted to do it a week earlier so as to give ourselves some time to fix anything that might break ahead of the EOY shutdown from w/c December 22nd.
Ubuntu 26.04 is a Long Term Support (LTS) release with a total of 15 years support: 5-years standard support, 5-years Expanded Security Maintenance (ESM), and 5 years of security coverage (for paid customers).
The snapshot so far is still powered by Kernel 6.17 and features Gnome Desktop 49. There’s NO visual difference compare to the last snapshot release. Though, you may keep an eye on this on-going release note page for the updates.
According to the road map, Ubuntu 26.04 will have 2 new default applications: Showtime video player, and Resources system monitor and task manager.
It will continue improving the NVIDIA on Wayland experience, introduce Security Protocol and Data Model (SPDM) based fingerprint authentication, add more control for TPM-backed full disk encryption (e.g., ability to add/remove PIN or passphrase after installation, re-encrypt a disk via Security Center), unified software management, and Ubuntu Pro on WSL.
And, it will sadly exclude Ubuntu MATE and Ubuntu Unity as the official flavors in next LTS, because the two flavors lack of maintainers and miss the deadline of LTS re-qualification.
NOTE: This is a development release that’s NOT ready for production use!
The .iso images for Desktop and Server, as well as Netboot tarball, WSL, and pre-install server images are available to download via the link below:
For desktop and education users, the snapshot also includes the .iso images for all the official flavors, which are available to download via the link below:
For Ubuntu MATE and Unity, the iso images are automated builds without maintainers behind them.
If you’ve already run your machine with Ubuntu 26.04 daily build or snapshot 1, then simply install all the available updates to get to the new snapshot.
For current Ubuntu 25.10, I’ve tried to upgrade to the new 26.04 Development release by first installing all updates:
sudo apt update && sudo apt full-upgrade
Restart if required, then run:
do-release-upgrade -d
For future releases, see the table below or the official release schedule.
| January 29, 2026 | Snapshot 3 |
| February 26, 2026 | Snapshot 4 |
| March 26, 2026 | Beta (mandatory) |
| April 16, 2026 | Final Freeze, Release Candidate |
| April 23, 2026 | Final Release |

After more than two months of Beta testing, System76 finally announced the release of Pop!_OS 24.04 LTS.
As the version number indicates, Pop!_OS 24.04 is based on Ubuntu 24.04, but features Linux Kernel 6.17 and its new COSMIC desktop environment.
Pop!_OS 24.04
Pop!_OS is developed by System76, a American Linux computer manufacturer. It features COSMIC desktop, which was previously a customized GNOME desktop, but now a standalone desktop environment built from scratch.
The new desktop environment is written in the Rust programming language for high performance and memory safety. It replaced Nautilus, Gnome Terminal, Gnome Text Editor, Totem with its own COSMIC specific files, terminal, text editor, and video player apps.
Pop!_Shop is replaced by COSMIC Store, which supports both Flatpak and Deb out-of-the-box. And, the GDM display manager is replaced by new COSMIC Greeter with a redesigned login appearance.
COSMIC Store
The new desktop improved window tiling support. It added a toggle in system tray indicator, allowing to tile all current workspace windows by single-click. The icon changes automatically according to the window tiling status. And, it supports drag’n’drop exchange window position in tiling mode.
Besides using indicator menu, it also support tiling windows via keyboard shortcuts, and tiling in per display basis.
The workspaces can now displayed in either vertical or horizontal orientation. Multiple displays can have separated or spanned workspaces. And, it supports pinning workspace and drag’n’drop re-arranging workspace or even moving to another display.
Pop!_OS 24.04 also improved multiple monitors support. Besides per display window tiling and multi-display workspaces mentioned above, it also improved the experience for displays with mixed HiDPI and standard resolutions.
Displays are automatically scaled based on pixel density and display scaling can be fine-tuned in Settings. And, it will remember your display settings and restore automatically next time you plug it in.
Moreover, it added hybrid graphics support. Apps request the discrete GPU will automatically run on the correct GPU, while user may right-click on app icon to choose which GPU to use at launch.
Other changes in Pop!_OS 24.04 include:
For more, see the official release note.
Pop!_OS 24.04 is available to download in its website via the link below:
It recommends 4 GB RAM, 16 GB disk space, and 64-bit ARM or X86_64 processors. While, NVIDIA edition asks for GeForce 16 series graphics or newer.
And for Pop!_OS 22.04 LTS, user may run the single command below in terminal to upgrade to Pop!_OS 24.04 LTS:
pop-upgrade release upgrade -f
Though it’s always recommended to back up your files first.
For users of Ubuntu MATE and Ubuntu Unity, the 2 Linux Distributions will NOT be the official flavors for the next Ubuntu 26.04 LTS.
Ubuntu announced the LTS qualifications for Resolute Raccoon in last week:
We haven’t seen LTS requalification requests from Ubuntu MATE nor Ubuntu Unity, so these will release subject to release team approval, and they will be non-LTS.
As you know, the Ubuntu flavors are the community maintained distributions with different desktop environments or specific intended use case. So far, Ubuntu has 10 official flavors, they are listed in this Ubuntu web-page.
Ubuntu always requires the official flavors to go through a qualification process for every releases, especially for LTS. For next Ubuntu 26.04 LTS, the following flavors have been approved with three year LTS qualification.
KUbuntu 24.04
KUbuntu is not mentioned in the announcement. And, I didn’t see the qualification request for KUbuntu 26.04 in the Technical Board.
The KUbuntu developer, Scarlett Gately Moore, was in a car accident in last July. Though back to work now, she needs a little help.
Rik Mills, another KUbuntu developer who’s also Ubuntu core developer, is actively building packages for Ubuntu 26.04 and backporting Plasma desktop and KDE frameworks for current Ubuntu release through KUbuntu PPAs.
IMO, KDE Plasma is so popular and maintainers are still actively working, there’s no reason to exclude KUbuntu 26.04 as one of the next official LTS flavors.
Ubuntu MATE 24.04
Ubuntu MATE is Ubuntu with MATE desktop environment, a continuation of the classic GNOME 2. It was firstly approved as official flavor when it was in version 15.04.
MATE in current Ubuntu releases is still at version 1.26, while the latest MATE 1.28 has been released for more than a year. Debian upstream has started packaging MATE 1.28 for Forky and Ubuntu 26.04, though Ubuntu MATE developer missed the LTS qualification.
According to the future of Ubuntu MATE discussion, it seems that the project lead, Martin Wimpress, is now having other interests and obligations (Nøughty Linux), so he didn’t apply the re-qualification requests.
For Ubuntu Unity, the official flavor since 22.10, the project lead Rudra Saraswat, is too busy because of university exams and tests.
Other members lack of knowledge to maintain the project, and Maik Adamietz asked for help by this thread in discrouse few months ago, but without luck. And, they didn’t even know the requalification process so missed the deadline for next 26.04 LTS.
Without Ubuntu MATE or Ubuntu Unity, Ubuntu 26.04 can install the 2 desktop environments from the system repositories, though they will be less stable due to lack of desktop specific maintenance.
According to this discourse page, 24.04 users may stay with it until 2034, by enabling Ubuntu Pro for security maintenance, though Canonical does not offer phone or ticket support for Community Flavors.
