Public bug reported:
Description: Ubuntu 18.04.5 LTS
Release: 18.04
I clicked the button to upgrade the system in the dialogue box that
popped up telling me that there is a new version of the OS I can upgrade
to.
After the Distribution upgrade was running for a short while, it showed
the following error message:
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'.
