Public bug reported: Description: Ubuntu 18.04.5 LTS Release: 18.04
I ran sudo do-release upgrade and expected to upgrade from 18.04 to 20.04. But this happened: 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 have looked at main.log and apt.log and removed some PPAs but it is still failing and I am unable to figure out why.
