This bug was fixed in the package unattended-upgrades - 1.9
---------------
unattended-upgrades (1.9) unstable; urgency=medium
[ Julian Andres Klode ]
* test_dev_release: Fix and enable test.
* Depend on python3-distro-info.
This is needed to make sure DEVEL_UNTIL_RELEASE actually works. We need
to fix up travis in addition to control, as it only knows about trusty
build dependencies.
* Import distro_info globally, and fix calculation of days.
The check was off by one: If you were 21 days away from the release,
it would not switch on, but tell you that it would not upgrade before
today.
* test_dev_release: Test Unattended-Upgrade::DevRelease=auto.
[ David Lang and Balint Reczey]
* Allow installing untrusted packages when APT::Get::AllowUnauthenticated
is set (Closes: #775469) (LP: #1167053)
[ Hans van Kranenburg and Balint Reczey]
* Clarify highly misleading Package-Blacklist option documentation
(Closes: #753892)
[ Balint Reczey ]
* test/test_dev_release.py: Fix missing mock attributes
* Leave the cache clean when returning from calculate_upgradable_pkgs()
When collecting upgradable packages the upgradable ones stayed in the
cache and they were upgraded together even when unattended-upgrades
was configured to perform upgrades in minimal steps.
Thanks to Paul Wise
* debian/tests/upgrade-all-security: Check if all security-updates are
applied and if old-autoremovable packages are kept
* Clear cache only when needed when checking black- and whitelists
* Add --no-minimal-upgrade-steps option
* Stop using untrusted package names as blacklists (LP: #1805447)
* Update copyright info
* Load modules lazily loaded by datetime.datetime.strptime() when u-u starts
When Python is upgraded to a new major version the the version running
unattended-upgrades can be removed as being newly unused causing a crash.
* Start service after systemd-logind.service to be able to take inhibition
lock
and handle gracefully when logind is down (LP: #1806487)
* List packages making reboot required in /var/run/reboot-required.pkgs

Bug description:
[Impact]
* Unattended-upgrades.service may crash due to starting earlier than dbus
and logind are up or due to logind failing to start.
* Unattended-upgrades.service not starting prevents installation of upgrades
on shutdown (when u-u is configured to do that) and also prevents gracefully
stopping running u-u _before_ shutdown as implemented in LP: #1803137. U-u is
still stopped gracefully after the shutdown transaction is started, but that
may let service restarts hang the upgrade process.
* The fix is adding an After service dependency on systemd-logind to ensure
starting u-u.service after logind at least tried to start and also changing
u-u-s to start even with logind's absence.
[Test Case]
* Stop systemd-logind and make it unable to start for example by
masking it:
root@bb-logind:~# ln -s /dev/null /etc/systemd/system/systemd-logind.service
root@bb-logind:~# systemctl daemon-reload
root@bb-logind:~# service systemd-logind stop
root@bb-logind:~# service systemd-logind status

Main PID: 1938 (code=killed, signal=TERM)
Status: "Processing requests..."
...
* Run u-u-s and observe it crashing in unfixed version and starting
with falling back to polling logind instead taking the inhibition lock
at its start:
root@bb-logind:~# /usr/share/unattended-upgrades/unattended-upgrade-shutdown
--debug
root@bb-logind:~# tail
/var/log/unattended-upgrades/unattended-upgrades-shutdown.log

[Regression Potential]
* The change to service ordering is unlikely to cause any issue, but
the graceful handling of missing logind involved a small-scale
refactoring of u-u-s's code. Extensive testing did not reveal
regressions in that area, but potential bugs may cause u-u.service
fail to start and affect graceful shutdown of u-u the same way as
detailed in [Impact].
