Using your test script on Xenial I discovered that after the reboot I needed to run 'sudo dpkg --configure -a' to finish the operations that unattended-upgrades was doing.
Further testing has revealed that there seems to be something wrong with Xenial while I'd been testing Yakkety. When running your script on Yakkety I saw that unattended-upgrades- shutdown.log was created and contained the following: bdmurray@clean-yakkety-amd64:~$ cat /var/log/unattended-upgrades/unattended-upgrades-shutdown.log 2017-05-24 14:56:03,095 WARNING - Unattended-upgrade in progress during shutdown, sleeping for 5s Progress: 50.1385 % (linux-headers-4.8.0-52) 2017-05-24 14:56:08,110 INFO - All upgrades installed While on Xenial unattended-upgrades-shutdown.log was an empty file and I did not see anything on the shutdown screen about the shutdown being paused. Could you confirm that Yakkety deals better with a reboot while unattended-upgrades is running?
