Using reboot did more of the same. At this point the Xenial version is 16.04.4 - we have a snapshot from 2019-05-28. unattended-upgrades was at 0.90ubuntu0.9 but salt config management upgrades to 1.1ubuntu1.18.04.7~16.04.3 once the machine has salt installed. We pretty much update a symlink which has two publish dates, 2019-05-28 (old) to 2019-09-04 (new). I'm not sure if that's playing a role but I do know 0.90ubuntu0.9 worked for me last time.
