Ubuntu 26.10 Beta Lands With Linux 7.3 Target and GNOME 51

Canonical's Ubuntu Release Team published the Ubuntu 26.10 "Stonking Stingray" beta on October 1, covering Desktop, Server, WSL and Cloud images as well as the official flavors. The team describes the images as reasonably free of showstopper image-build or installer bugs and representative of the features intended for the final release.

The final Ubuntu 26.10 release is still expected on October 15, 2026. This remains pre-release software, so the beta is primarily for testing and bug reporting rather than production systems.

Canonical's Kernel Team originally targeted Linux 7.2 for Ubuntu 26.10, but on September 1 it upgraded the target to Linux 7.3 after the upstream kernel schedule remained on track. Canonical said the newer target is intended to keep 26.10 aligned with recent upstream hardware support.

That target change happened late enough in the cycle to matter for PC users testing very new hardware, but it is not a promise that every device-specific compatibility issue is solved. Hardware support still depends on the individual kernel driver, firmware and userspace stack.

Ubuntu Desktop's published 26.10 roadmap says the release will ship GNOME 51. Canonical is positioning this interim release partly as groundwork for Ubuntu 28.04 LTS, rather than treating every change as an isolated one-release experiment.

Because 26.10 is an interim release, users on the 26.04 LTS branch do not need to move simply because the beta is newer. The beta is most useful now for developers, testers and users who specifically need to evaluate the new desktop and hardware stack before the final image arrives.
