If you are still running Ubuntu 25.10 "Questing Quokka" on your machine, this is your official wake-up call. As of July 9th, 2026, Canonical has officially dropped support for this release. This means no more official software updates, zero bug fixes, and—most importantly—no more critical security patches.
Leaving your system without updates exposes it to emerging security vulnerabilities. Fortunately, the upgrade path to the highly anticipated Ubuntu 26.04 LTS (Resolute Raccoon) is fully open, offering a more stable, secure, and modern desktop experience. Here is everything you need to know about why you must switch and how to do it seamlessly.
Why is Ubuntu 25.10 EOL Already?
For those unfamiliar with Canonical’s release cadence, Ubuntu 25.10 was a standard short-term release launched on October 9th, 2025. These interim versions are engineered to showcase cutting-edge features but only come with a strict nine-month support window.
During its run, the Questing Quokka introduced users to a Wayland-only session powered by the Linux 6.17 kernel series and GNOME 49. Now that its time is up, running this version leaves your desktop vulnerable to threats over time.
The Big Leap Forward: What’s New in Ubuntu 26.04 LTS?
Upgrading from an interim release to a Long Term Support (LTS) milestone brings massive upgrades to your workflow. Ubuntu 26.04 LTS provides enterprise-grade stability backed by 5 years of standard support, which can be extended up to 10 years via a free Ubuntu Pro account. The adoption of this LTS foundation is already widespread, even anchoring structural framework updates in specialized distributions like Armbian 26.5.
Stepping up to the Resolute Raccoon gives you immediate access to performance enhancements:
-
Mainline Linux Kernel 7.0: Offers superior hardware compatibility, improved power management, and faster file-system execution right out of the box.
-
GNOME 50 Desktop Environment: Delivers a refined, fluid user interface with overhauled workspace management and better windowing automation.
How to Upgrade to Ubuntu 26.04 LTS
Canonical has fully cleared the upgrade path, allowing you to transition directly from your existing setup. The entire process is straightforward and typically takes less than 30 minutes depending on your internet connection.
Before executing any commands, make a comprehensive backup of your essential files, configurations, and projects to an external drive or cloud storage. Once your data is safe, follow these steps:
- Open your terminal application (
Ctrl+Alt+T). -
Run the command
sudo apt update && sudo apt dist-upgradeto ensure your current system packages are fully up to date. - Reboot your computer if any major system components were updated.
-
Open the terminal again and execute
sudo do-release-upgradeto initiate the official upgrade wizard.
Follow the on-screen prompts, confirm the package downloads, and allow the system to install the new core packages. Once completed, restart your machine to welcome your brand-new LTS desktop.
Conclusion
Sticking with an expired operating system is a risk not worth taking, especially when a superior, long-term alternative is freely available. Upgrading to Ubuntu 26.04 LTS doesn't just shield you from security risks—it drastically elevates your daily computing performance with Linux Kernel 7.0 and GNOME 50. Don't wait until security flaws disrupt your workflow; back up your data and make the switch today.
Are you planning to upgrade your desktop immediately, or are you deploying this new LTS release on your homelab clusters?
