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

[Balint Reczey]

The apport issue seems to be due to a bug in xenial's shared-mime-info:

root at xenial-test:/home/rbalint# time apt-get install -y --allow-downgrades --reinstall apport=2.20.1-0ubuntu2
Reading package lists... Done

The following packages were automatically installed and are no longer required:

This takes ~2s on zesty:

This may worth further investigation and possibly an SRU.
