Public bug reported:
I am trying to upgrade from 16.04 to 18.04 and the process fails without
displaying any error messages (it just says "Aborting") so I cannot
troubleshoot. I have seen Bug #1775883 but I do not have any PPAs
installed (based on ls /etc/apt/sources.list.d at least)
Can you please help me debug the problem?
