unattended-upgrades (0.92ubuntu1.3) yakkety; urgency=medium
* The systemd unit needs to be an ExecStop since it is is activated on
shutdown. Otherwise, it will get scheduled after completion of
the local-fs.target. In the case where /var is a separate
filesystem, unattended-upgrade-shutdown will hang until timeout
since /var/run is expected but no longer there (LP: #1654600)
