I am trying to upgrade from Ubuntu 20.04 to 22.04 yet when running the sudo do-release-upgrade I get the error message:
Could not calculate the upgrade
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 checked /var/log/dist-upgrade/main.log which contains the following message:
ERROR Dist-upgrade failed: 'Broken packages after upgrade: evolution-data-server, gnome-control-center, libgirepository-1.0-1, ubuntu-desktop'
I'm not familiar with these packages and they look necessary. Is it safe to run ppa-purge or sudo apt remove on them? How should I proceed from here?
