Following a bug in ubuntu-release-upgrader which was causing Ubuntu Studio 22.04 LTS to fail to upgrade to 24.04 LTS, we are pleased to announce that this bug has been fixed, and upgrades now work.

As of this writing, this update is being propagated to the various Ubuntu mirrors throughout the world. The version of ubuntu-release-upgrader needed is 24.04.26 or higher, and is automatically pulled from the 24.04 repositories upon upgrade.

Unfortunately, while testing this fix, we noticed that, due to the time_t64 transition which prevents the 2038 problem, some packages get removed. We have noticed that, if upgrading from 22.04 LTS to 24.04 LTS, the following applications get removed (this list is not exhaustive):

• Blender
• Kdenlive
• digiKam
• GIMP
• Krita (doesn’t get upgraded)

To fix this, immediately after upgrade, open a Konsole terminal (ctrl-alt-t) and enter the following:

sudo apt -y remove ubuntstudio-graphics ubuntustudio-video ubuntustudio-photography && sudo apt -y install ubuntustudio-graphics ubuntustudio-video ubuntustudio-photography && sudo apt upgrade

If you do intend to upgrade, remember to purge any PPAs you may have enabled via ppa-purge so that your upgrade will go as smooth as possible.

We apologize for the inconvenience that may have been caused by this bug, and we hope your upgrade process goes as smooth as possible. There may be edge cases where this goes badly as we cannot account for every installation and whatever third-party repositories may be enabled, in which case the best method is to back-up your /home directory and do a clean installation.

Remember to upgrade soon, as Ubuntu Studio 22.04 goes End Of Life (EOL) in April!
