Public bug reported: do-release-upgrade -m desktop fails with the following message:
Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade. 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'. main.log shows: "ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'" sudo apt-mark showhold doesn't show anything held. I have removed all the 3rd party PPAs and applications, muon and discover say I have no pending updates, and there are no locked packages. I have some searching around and it looks spookily similar to bug #1875523. Could it be a regression?
