[Bug 2053115] [NEW] cannot upgrade from 20.04 to 22.04

[Thomas Locher]

Public bug reported:

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 removed basically all PPAs but it still doesn't work.
