Title:
  upgrade from 20.04 -> 22.04 fails due to python conflict from focal-
  updates repo

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

Bug description:
  I assumed this was due to me installing some random ppa from
  somewhere, but I eventually tracked this down to a conflict between
  python3-ldb and libldb2 from official repositories:

    2:2.4.4-0ubuntu0.20.04.1 from the focal-updates repo 
    2:2.4.4-0ubuntu0.1 from the jammy-updates repo

  I found this by updating apt with the jammy repos and running "apt-
  cache policy" on the broken packages, but you can see the package
  lists in the official locations for verification:

    https://packages.ubuntu.com/focal-updates/allpackages
    https://packages.ubuntu.com/jammy-updates/allpackages

  This is not the only package, there are a number of python-related
  packages with this naming scheme, and I can't seem to get apt to
  resolve all of them.  I can downgrade to the python version
  (2:2.0.8-2) in focal main, but then do-release-upgrade complains that
  I have updates.

  I have worked around this by removing those packages (which also transitively removes: gnome-control-center gvfs-backends libsmbclient samba-libs ubuntu-desktop ubuntu-desktop-minimal vlc-plugin-samba), and then running the upgrade.  But, this is clearly a bug in the upgrade process.
