The problem is occurring because ubuntustudio-pulseaudio-config is incompatible with the ubuntu-desktop metapackage as, for some reason, ubuntu-desktop has pipewire-audio as a hard dependency which has pipewire-alsa as a hard dependency. This means that the bug is really in ubuntu-meta and not in ubuntustudio-installer due to a package conflict, and a hard dependency in a metapackage that shouldn't exist.
It's unlikely this will be fixed in 23.04, but it might get fixed in time for 23.10, but we'll see. I can make no guarantees as I only oversee Ubuntu Studio. Unfortunately, Ubuntu Desktop users will have to remain on PipeWire and not use the ubuntustudio-pulseaudio-config package due to this discrepancy. This also means that Ubuntu Desktop 23.04 cannot and should not be used for professional audio. ** Package changed: ubuntustudio-installer (Ubuntu) => ubuntu-meta (Ubuntu) ** Also affects: ubuntu-meta (Ubuntu Lunar) Importance: Undecided Status: New ** Also affects: ubuntu-meta (Ubuntu Mantic) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/2033440 Title: ubuntustudio-installer: error occurred while applying changes Status in ubuntu-meta package in Ubuntu: New Status in ubuntu-meta source package in Lunar: New Status in ubuntu-meta source package in Mantic: New Bug description: I have installed successfully the standard Ubuntu 23.04 (on a 500 GB external USB drive). Immediately after the installation, I have also installed with apt the "ubuntustudio-installer" package. In the dialog provided by the ubuntustudio-installer, I have selected the following metapackages: - linux-lowlatency - ubuntustudio-lowlatency-settings - ubuntustudio-performance-tweaks - ubuntustudio-audio - ubuntu-pulseaudio-config and pressed "Modify installed Package Selection" After a while a "qaptbatch" dialog has appeared with title "Commit Error" and message "An error occurred while applying changes" So the installation has failed. Then I have tried to manually install each metapackage in the list above with apt and every package was installed successfully.
