Public bug reported:
Error msg:
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'.
Nothing interesting is logas as far as I can tell.
