Alarge family of Ubuntu Linux desktops is ready to join Ubuntu testing week starting on June 27, 2025. On this occasion, all seven Ubuntu flavors will release their beta version for public testing before the official final stable release.
In the wake of this event, Ubuntu flavors has requested the community to participate and help them find any bugs. With all the help, they would be able to fix all possible issues in the upcoming week before the final release.

Since the upcoming v20.04 is the next long-term release, it’s crucial for all variants to be tested and ensure the removal of bugs as much as possible.
