Ubuntu 25.10 Beta Released, Ready for Testing
It’s time to get testing — or do I mean questing? — as the beta release of Ubuntu 25.10 (Questing Quokka) is available to download. The Ubuntu 25.10 Beta brings a number of user-facing changes to the desktop, the majority of which come via the GNOME 49 release. There’s an accessibility menu on the login screen, media controls on the lock screen, and a Yaru theme update with new icons and smoother spinner animation on the boot screen.

Daily Kos ☛ Ubuntu Questing Quokka Beta is Out
Several versions are out. The main desktop version came out much later in the day than Ubuntu Studio, which I therefore tried first. No worries here. Now you and I can get the regular distro from the Ubuntu 25.10 (Questing Quokka) Beta page.
Let’s review the download and installation process, which works the same way for any of the Betas of any of the *ubuntu variants.
Use a computer with the fastest wi-fi you can manage. In my case, that means an 11-minute download, whereas one of my older computers would have taken hours. Also a fast USB 3.2 drive, when you install the .iso file to it. DO NOT install any of these Betas on a production computer, where a serious bug could result in data loss. Check whether your installation target is compatible with Ubuntu. linux-hardware.org

Ubuntu 25.10 Questing Quokka Is Now in Beta Testing
Canonical, the company behind the popular Ubuntu Linux distribution, has officially released the beta version of Ubuntu 25.10, codenamed "Questing Quokka". This is a big deal because it's the last interim release before the next long-term support version, which is slated for April 2026.
This beta release includes a bunch of updated core packages and a modern Linux 6.17 kernel, which should mean better performance and hardware support. You'll also find the recently released GNOME 49 desktop environment, which brings a refreshed look and new applications.
This is also the first time in a long time that Ubuntu is replacing some of its default apps. For example, it's ditching Eye of GNOME for Loupe, a new image viewer written in Rust that's designed for faster, smoother performance with GPU-accelerated rendering. Similarly, the old GNOME Terminal is being replaced with Ptyxis, a modern terminal emulator that's great for both developers and power users.

What's new in the Ubuntu 25.10 beta release could surprise some users
With Ubuntu 25.10 on the horizon, you might be curious about what will be included. Although a good number of features were added during the alpha phase of the development process, the just-released beta adds a few features that could be eye-openers to longtime (and new) users.
Keep in mind that any Ubuntu version ending in .10 is a short-term (aka "interim") release candidate, which means it only gets roughly one year of support. If you prioritize long-term support, those interim releases are probably not for you.
