[Bug 2084342] [NEW] Trying to upgade from 20.04 to 22.04 but getting an un clear error

[verajm@gmail.com]

Public bug reported:

as said, I'm trying to upgrade but I'm constantly getting this error


An unresolvable problem occurred while calculating the upgrade. 

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'.

I've tried removing some software no longer needed, also disabling all PPAs but no luck
