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

[Balint Reczey]

We discussed the test with Brian, and ending in inconsistent states can
still occur when running u-u manually/via cron.

In those cases the apt fix does not protect dpkg from being terminated early.
When running u-u manually or via cron it is recommended to use workaround 3. from #19, i.e. running u-u like that:
 systemd-inhibit --what=shutdown,handle-hibernate-key --mode=block /usr/lib/
