[Bug 2137158] Re: trying to update from 20.04 to 22.04

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Bug reporting is about finding & fixing problems thus preventing future
users from hitting the same bug.

I suspect a Support site would be more appropriate, e.g.
https://answers.launchpad.net/ubuntu. You can also find help with your
problem in the support forum of your local Ubuntu community
http://loco.ubuntu.com/ or asking at https://askubuntu.com or
https://discourse.ubuntu.com/t/welcome-to-support-and-help/49951), or
for more support options please look at
https://discourse.ubuntu.com/t/community-support/709.

Title:
  trying to update from 20.04 to 22.04

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

Bug description:
  All I get is:
  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. 

  If none of this applies, then please report this bug using the 
  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
  you want to investigate this yourself the log files in 
  '/var/log/dist-upgrade' will contain details about the upgrade. 
  Specifically, look at 'main.log' and 'apt.log'. 

  so far I've removed everything from sources.d entirely. nothing left
  in there. Not sure why it's giving me this
