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.

Title:
ubuntustudio-installer: error occurred while applying changes
Status in ubuntu-meta package in Ubuntu:

Status in ubuntu-meta source package in Lunar:

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.
