[Bug 2033440] Re: ubuntustudio-installer: error occurred while applying changes

[Marco Frailis]

Thank you for updating the documentation, that's exactly what was misleading.

Just as a feedback: installing manually the metapackages listed in the
ubuntustudio-installer worked fine. The ubuntu-desktop metapackage was
probably automatically uninstalled (it is no more instlled in my
system), but during the manual installation process I did not notice any
removal of other critical system packages. So now I have an Ubuntu
Studio over a Vanilla Ubuntu Gnome, with pulse-audio + jack, and a low
latency kernel.

To me, your answer closes the issue.

Thanks a lot.

  ubuntustudio-installer: error occurred while applying changes

Status in ubuntu-meta package in Ubuntu:

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.
