Public bug reported: I am receiving this error log:
Calculating the changes Could not calculate 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'.
