[Bug 1798216] [NEW] Upgrade from 16.04 to 18.04 fails with message "Aborting"

[Huji Lee]

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?
