The developer team started the development of Ubuntu 25.10 in last week. Now the release schedule and daily build live CD image are out!
Ubuntu 25.10, code-name Questing Quokka, is the next Ubuntu version planned to be released on October 09. It’s a short term release with 9-month support circle.
If everything goes well, it will feature GNOME 49 desktop and the latest Linux Kernel (probably v6.17 according to Kernel release interval).
