[Bug 2036340] Re: Failure to upgrade Ubuntu 20.04 "could not find a distribution template for Ubuntu/focal"

Reviewing the files from your upgrade attempt, you have installed
pipewire packages from the pipewire-debian/pipewire-upstream PPA. Some
of the packages installed are newer than those in the official archive,
which is keeping some pipewire-related packages installed which then
prevents the upgrade from being calculated. Please try using the ppa-
purge tool to remove packages installed from ppa:pipewire-
debian/pipewire-upstream by running ppa-purge -s ppa.launchpad.net -o
pipewire-debian -p pipewire-upstream. After that you can try upgrading
again and if it still fails open a new bug report. Thanks and good luck!

Title:
  Failure to upgrade Ubuntu 20.04 "could not find a distribution
  template for Ubuntu/focal"

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  I tried to upgrade my Ubuntu using the Sofware Update interface app
  (as suggested by the app itself).

  The app just fails to upgrade and suggests to use the bug-report, the
  logs show this error "could not find a distribution template for
  Ubuntu/focal" and another one about ubuntu-desktop being corrupted
  after the install.

  Sorry if this is a bad report, I have no idea what is exactly failing.
