Ubuntu 26.04.1 Released – How 24.04 Users Can Upgrade Early with a Single Command

What is Ubuntu 26.04.1?

Ubuntu 26.04.1 LTS "Resolute Raccoon" is a point release that does not add new features but repackages all security updates and bug fixes delivered through the stable channel since the original 26.04 launch on April 23. The new installation media includes every update up to August 25, 2026, and is available for all eight official flavors (Kubuntu, Xubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Studio, Ubuntu Kylin, Edubuntu, Ubuntu Cinnamon). Support periods remain 5 years for Desktop/Server/Cloud/Core and 3 years for the other flavors, with ESM extensions. No new HWE kernel is included; the next HWE kernel arrives with 26.04.2.

Key fixes in 26.04.1

Desktop experience : resolved crashes in Mutter when hot‑plugging similar monitors, fixed perpetual spinning mouse pointer after app launch, corrected cursor anomalies in pop‑ups, repaired touch‑screen drag‑and‑drop, and addressed several Nautilus crashes (memory corruption, Docker bookmark, icon scaling). PackageKit now avoids accidental dependency removal and fixes a TOCTOU security race.

Developer‑focused : the severe performance regression of Stable Diffusion XL (SDXL) inference has been fixed, restoring local AI‑drawing speed.

Hardware compatibility : Qualcomm X1E speaker overload shutdown issue and Intel IPU7 unsigned‑module secure‑boot failure are patched; GTX 580/595 driver updates prevent sleep‑related crashes, and firmware updates for Realtek, Intel, MediaTek, Qualcomm Wi‑Fi, and Cirrus audio devices are included.

Installation and architecture : RISC‑V earlycon=sbi boot failure and desktop‑flavor kernel configuration errors are fixed; NoCloud password format and Netboot kernel file permissions have been corrected. The new ISO incorporates all these fixes.

Upgrade decision guide

If you already run 26.04 LTS, simply apply updates via the Software Updater – no ISO download or reinstall needed.

If you are on 24.04 LTS and prefer to wait, let the automatic upgrade prompt appear in a few weeks.

If you are on 24.04 LTS and want to upgrade immediately, run the single supported command do-release-upgrade -d.

For fresh installations or installing for a friend, download the new 26.04.1 ISO and install.

New hardware (Wi‑Fi 7, latest GPUs) should wait for 26.04.2 because 26.04.1 does not contain a new HWE kernel.

How to upgrade early

Backup critical data – create a Timeshift snapshot or at least copy /home and key configuration files.

Check your cgroup version; if you previously switched to cgroup v1, follow the earlier "Ubuntu 26.04 upgrade pitfalls" guide to avoid upgrade rejection.

Ensure at least 10 GB of free disk space.

Run the upgrade in a terminal: do-release-upgrade -d and follow the prompts.

After the upgrade, execute sudo apt update && sudo apt upgrade to apply any remaining updates, then reboot.

The -d flag enables the development/new‑version channel, which the Ubuntu team uses to allow early upgrades before the automatic prompt becomes available. It is an officially supported method, not a hack.

Missing HWE kernel

HWE (Hardware Enablement) kernels are introduced in point‑release .2 versions. 26.04 shipped with kernel 7.0; 26.04.1 retains this kernel, while 26.04.2 (expected early 2027) will bring the next HWE kernel (likely 7.1+). Users needing newer kernel support for Wi‑Fi or GPU should either wait for 26.04.2 or use a Mainline PPA.

FAQ

Do I need to reinstall the ISO? No – just update via the Software Updater.

Is upgrading from 24.04 to 26.04.1 stable? The delayed automatic prompt ensures patches have settled; the manual -d upgrade follows the same tested channel, but backing up first is recommended.

Can I roll back? If you created a Timeshift snapshot before upgrading, you can revert; otherwise there is no official one‑click rollback.

Can I stay on 24.04? Yes – mainstream support lasts until 2029 with three more years of security updates.

How does 26.04.1 relate to 26.10? 26.04.1 is the stable maintenance track; 26.10 (released October 15) is the “edge” release with GNOME 51, Myna AI, and other new features.

Conclusion

Ubuntu 26.04.1 is a classic maintenance update that bundles four months of fixes without new features or a new kernel. For 24.04 users, the choice is simple: wait a few weeks for the automatic prompt if you value stability, or run do-release-upgrade -d now after backing up.
