Public bug reported: I don't know if it's an actual bug or not. Using Release 20.04. --------------------------------------------------------------------------------------------------------------------------------------------------------- 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'. ----------------------------------------------------------------------------------------------------------------------- Thanks for checking.
