Ubuntu Studio 22.04 LTS to 24.04 LTS upgrade issues
Ubuntu Studio 24.04 LTS allows users to choose between PipeWire (default) and legacy PulseAudio/JACK settings. To facilitate this option, PipeWire is a "soft" dependency, meaning it can be uninstalled without breaking core functionality. However, this flexibility confuses the
ubuntu-release-upgradetool during the upgrade process, resulting in package conflicts and upgrade failures. In a blog post, the Ubuntu Studio team wrote:
"Currently, we are working with Canonical's Ubuntu Basics team to explore how to force ubuntu-release-upgrade to install PipeWire in Ubuntu Studio without Ubuntu Studio having a hard dependency on PipeWire."
2078639One of the specific manifestations of this problem is detailed in Launchpad Error Report
. Analysis by developer Julian Andres Klode shows that the upgrade process attempts to remove plasma-desktop and ubuntustudio-desktop due to complex dependencies involving PulseAudio and PipeWire. Impact
A large number of Ubuntu Studio users cannot directly upgrade the system. This creates frustration and can force users to take more laborious workarounds, such as a brand new installation.
Possible Solutions
As of this writing, there are some possible solutions.
1. ubuntu-release-upgrade special treatmentDevelop a special handling in ubuntu-release-upgrade to force installation of pipewire-audio, specifically for Ubuntu Studio upgrades. This will keep the option for the user to switch back to PulseAudio later. 2. Hard dependency on PipeWire Making pipewire-audio a hard dependency for Ubuntu Studio effectively eliminates the ability to revert to classic PulseAudio/JACK settings. This ensures a smooth upgrade, but sacrifices user choice. 3. Disable direct upgrade Remove the upgrade notification and officially declare that it does not support direct in-place upgrade from Ubuntu Studio 22.04 LTS to 24.04 LTS. This avoids immediate problems, but requires additional upgrade paths such as a brand new installation. The Ubuntu Studio team does not want to do any of these measures. They hope to find a better solution soon. If you try to upgrade Ubuntu Studio, you may need to wait for this issue to be resolved.
