[Bug 1971030] Re: can not upgrade from 20.04 to 22.04

[Nick Rosbrook]

Hi,

Did you try using ppa-purge to remove those packages as suggested?

Also, looking at your /etc/apt/sources.list (included in the attached
VarLogDistupgradeAptclonsystemstate.tar.gz), it appears you do not have
focal-updates (or focal-security) enabled, so your packages are out of
date and may be causing problems for the upgrade.

Please enable focal-updates and focal-security, run `sudo apt update`
and `sudo apt upgrade`. Also please try ppa-purge if you haven't
already, and then try the upgrade again.

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

Bug description:
  I'm trying to upgrade from 20.04 to 22.04 but I got this message

  This was likely caused by: 
  * Unofficial software packages not provided by Ubuntu 
  Please use the tool 'ppa-purge' from the ppa-purge 
  package to remove software from a Launchpad PPA and 
  try the upgrade again.
