Ubuntu 26.04 LTS Released: Major Desktop Updates with GNOME 50 and Linux 7.0

Ubuntu 26.04 LTS was released on April 23, 2026, under the codename Resolute Raccoon. This is the new long-term support release, with standard support through April 2031. If you use Ubuntu Pro, security maintenance can be extended to 10 years.

If you are upgrading from Ubuntu 24.04 LTS, this is more than a routine release. It also folds in the major changes introduced across 24.10, 25.04, and 25.10. So this article works best as a quick guide to what is worth checking before you upgrade.

If you only want the biggest takeaways from this release, remember these four points first:

GNOME 50 has landed in an LTS release, bringing clearer improvements to desktop experience and display support
Linux kernel 7.0 becomes the new baseline, refreshing both hardware support and the long-term maintenance base
Ubuntu Desktop has now fully moved to Wayland
The default app set has been refreshed across the board, with major updates to Firefox, LibreOffice, Thunderbird, and GIMP

1. Start with the key updates

Ubuntu 26.04 LTS is a long-term support release with standard support through 2031-04
The desktop environment has been updated to GNOME 50
The generic kernel has moved to Linux kernel 7.0
Ubuntu Desktop now provides only a Wayland session
Older versions cannot jump directly to 26.04

If you are still on Ubuntu 22.04 LTS or 25.04, the official recommendation is to upgrade to Ubuntu 24.04 LTS or 25.10 first, then continue to 26.04 LTS.

2. Biggest change #1: GNOME 50 is now in LTS

The most visible desktop-side change this time is that GNOME 50 has finally entered an LTS release. For most users, the value is not one flashy standalone feature, but a smoother desktop experience overall:

Better usability on small screens and narrow windows
Notifications can be grouped by app
Continued improvements to HDR, VRR, and fractional scaling
Better smoothness and stability in remote desktop, Wayland, and NVIDIA-related scenarios
Stronger accessibility support, including clear updates to the Orca screen reader

Ubuntu has also added a few practical changes of its own:

GNOME Shell global search can directly find available snap apps
Web searches can also be triggered directly from search
The Yaru theme continues moving closer to upstream GNOME styling
Permissions, file access, and drag-and-drop behavior for snap apps feel more natural on the desktop

If you mainly use the desktop edition, the real point of this LTS is not a dramatic visual overhaul. It is that many small frictions from the past have been polished away together.

3. Biggest change #2: the default apps got a broad refresh

Compared with 24.04 LTS, the built-in app set in 26.04 LTS has been updated in a big way:

Firefox moves to 150
LibreOffice goes from 24.2 to 25.8
Thunderbird moves to 140
GIMP jumps from 2.10 to 3.2

There are also several replacements that matter in day-to-day use:

The PDF viewer is now Papers, replacing Evince
The image viewer is now Loupe
The terminal is now Ptyxis
The system monitor is now Resources
The default video player is now Showtime

The direction behind these changes is clear: Ubuntu is leaning more fully into a new generation of GNOME applications built on GTK4, libadwaita, and in some cases Rust-based rewrites.

4. Biggest change #3: Wayland is now the only desktop session

This is the most important change for many long-time users.

The shift that started in 25.10 is now fully settled in 26.04 LTS: Ubuntu Desktop runs only on the Wayland backend, because GNOME Shell can no longer run as an X.org session.

That does not mean old applications suddenly stop working. The official notes make it clear that X.org applications can still run through the XWayland compatibility layer. But if your workflow still depends on older graphics drivers, certain remote desktop methods, screen recording tools, or input method details, this is still something you should verify before upgrading.

5. Biggest change #4: Linux kernel 7.0 and the lower stack move forward together

The GA generic stack in Ubuntu 26.04 LTS moves from Linux 6.8 to Linux 7.0, and the HWE stack is also unified on 7.0.

Among the lower-level changes highlighted by Ubuntu, the most relevant ones for general users and operators are:

Crash dump is enabled by default on both desktop and server
sched_ext introduces a new scheduler extension model that lets developers implement scheduling policies with eBPF
The linux-lowlatency binary package is being retired, replaced by linux-generic plus the user-space lowlatency-kernel package for low-latency tuning
The amd64v3 architecture variant is available as an option, but still opt-in by default

If your machine is relatively new, amd64v3 is worth keeping an eye on. The official notes give this enablement method:

1
2
3


echo 'APT::Architecture-Variants "amd64v3";' | sudo tee /etc/apt/apt.conf.d/99enable-amd64v3
sudo apt update
sudo apt upgrade

That said, it is not enabled automatically. Ubuntu is still prioritizing compatibility first.

6. Hardware requirements and install baseline

The official recommended baseline for Ubuntu Desktop 26.04 LTS is:

A 2 GHz dual-core processor or better
At least 6 GB RAM
At least 25 GB of available storage

If your machine is on the lighter side, the official recommendation is to consider Ubuntu flavors such as Xubuntu or Lubuntu.
The server edition has a lower floor. The documentation notes it can start from 1.5 GB RAM and 4 GB of storage, though the real requirement still depends on your workload.

7. Who should prioritize upgrading

If you are already on 24.04 LTS and want the following, 26.04 LTS is worth a close look:

A full-generation desktop stack refresh instead of minor patching
More mature Wayland and display support
A more up-to-date default application set
A newer kernel with a longer support runway

But if you still depend heavily on older X11 workflows, special drivers, or custom desktop extensions, or if your production environment is extremely conservative about changes, it is still best to do a compatibility pass before upgrading.

8. One-line summary

The value of Ubuntu 26.04 LTS is not one especially flashy headline feature. It is that Ubuntu has rolled two years of desktop, kernel, application, and compatibility progress into a new LTS baseline all at once.

If you want the shortest possible judgment, it is this: this is an Ubuntu LTS release that feels broadly newer and more stable as a whole, rather than one built around a single standout feature.
