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

[Brian Murray]

I test this again in the following manner, installed apt and unattended-
upgrades from Balint's PPA, then modified /etc/apt/apt.conf.d/20auto-
upgrades so that APT:Periodic::Unattended-Upgrade was "1". I then ran
"sudo service apt-daily-upgrade start" and ran the u-u-reboot.sh script
I've mentioned before.

After the reboot I ran 'sudo apt-get update' and 'sudo apt-get upgrade'
which returned:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure
-a' to correct the problem.

This is the problem we are trying to avoid. I'll attach /var/log
/unattended-upgrades/unattended-upgrades.log and u-u-dpkg.log.
