Public bug reported:
After upgrade failed due to 3rd party sources I unticked/deselected
google, TeamViewer and graphics/ubuntu/bionic/main (sorry, not precise -
from my notes). Then I power cycled the PC.
I'm running upgrade from limited user account and authenticating when
requested.
Do I need to install from downloaded image?
Full error message follows.
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'.
