[Bug 2137158] [NEW] trying to update from 20.04 to 22.04

[Marc E Lytle]

Public bug reported:

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
