[Bug 1690980] Re: unattended-upgrades does not block shutdown of system, as it is designed to

[Balint Reczey]

@Brian: Thanks! Verbose/debug mode seems to cause the errors and
possibly the inconsistent state, too, due to u-u crashing early.

The other case where you can still get an inconsistent state is when u-u
takes more than 15 minutes to install all the packages in a way that it
can't be interrupted in the last 5 minutes.

Do you have something in the logs to verify one of the theories?
