[Bug 1898570] [NEW] ran update from 18 to 20 from GUI

[Chris Morris]

Public bug reported:

This was actually my second try after running "do-release-upgrade"
failed thusly:


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'.
