Public bug reported:
What Happened:
When upgrading from 18.10 -> 19.04 about 10 minutes into the upgrade a dialog
box shows up to remove old packages at this point the HDMI output and ssh
servers are disabled so the only way to continue the upgrade is to physically
go to the machine and plug in a VGA cable to an old monitor.
What should have happened:
Current Display output (In this case HDMI) and ssh access should be maintained
during an upgrade of a system. Especially when there are user prompts.

on again with both VGA and HDMI connected restores the display.
