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

[Brian Murray]

I built a new version of unattended-upgrades with Balint's patch and
tested it on an Ubuntu 16.04 system. I used the attached modified
version of the reboot script provided by Ethan and saw the following in
the terminal which I had run "sudo unattended-upgrade --debug
--verbose":

Preparing to unpack .../libc6-dev_2.23-0ubuntu9_amd64.deb ...
Unpacking libc6-dev:amd64 (2.23-0ubuntu9) over (2.23-0ubuntu3) ...
Connection to clean-xenial-amd64.local closed by remote host.
Connection to clean-xenial-amd64.local closed.

The system ended up in a state where I had to run 'sudo dpkg --configure
-a' and then 'sudo apt-get -f install'.
