Title:
Unattended-upgrades may keep running after unmounting local
filesystems in InstallOnShutdown mode
Status in unattended-upgrades package in Ubuntu:
Fix Released
Status in unattended-upgrades source package in Cosmic:
Fix Committed
Bug description:
[Impact]
* Unattended-upgrades may keep running during shutdown even beyond
unmounting local filesystems potentially leaving a broken installation behind.
* The fix reverts the original fix of LP: #1778219 and applies a different
one starting unattended-upgrades-shutdown _before_ the shutdown transaction
starts/
[Test Case]
* Run unattended-upgrades in InstallOnShutdown mode and observe it
being finished installing a few packages _before_ the shutdown
transaction starts:
$ lxc launch ubuntu:18.10 cc-uu-onshutdown
Creating cc-uu-onshutdown
Starting cc-uu-onshutdown
$ lxc shell cc-uu-onshutdown

root@cc-uu-onshutdown:~# apt update -qq
33 packages can be upgraded. Run 'apt list --upgradable' to see them.

[Regression Potential]
* The change reverts the behavior of unattended-upgrades-shutdown to
be close to the behavior observed in Ubuntu 18.04, blocking the
shutdown process reliably until is unattended-upgrades finished, but
it starts _before_ shutdown triggered by the PrepareForShutdown()
signal. Due to the shutdown not fully starting yet users may not get
visual notification of unattended-upgrades running.
In my testing on Bionic when a logged-in user shuts down the system
when InstallOnShutdown is configured the user is dropped out to the
login manager and nothing shows that u-u is running behind the screens
for 30s, when the inhibition timer expires and u-u is starting to
gracefully stop and the usual text appears after the login manager
exits and plymouth shutdown screen is shown. The fix would be the
login manager also monitoring PrepareForShutdown() and exiting (LP:
#1803581).
On Xenial (with Unity) starting shutdown from the graphical session
does not log the user out nor show any progress on the shutdown until
the inhibition timer expires which is confusing. Users should be
logged out on PrepareForShutdown() (LP: #1803581).
* The reversion of unattended-upgrades.service was not complete in
u-u 1.7 and needed a further fix in 1.7ubuntu1 (which fix is already
included in 1.5ubuntu4). This part may be source of potential
regressions.
* The fix itself rewrites big part of unattended-upgrades-shutdown
and this rewrite could cause regressions in running unattended-
upgrades in InstallOnShutdown mode, but also this mode was extensively
tested.
* The fix includes increasing logind's InhibitDelayMaxSec to 30s to
give u-u enough time to gracefully stop in normal mode and install
packages in InstallOnShutdown mode. The delay is global, thus any
other program holding the lock can delay shutdown or sleep by 30s
instead of the original 5s default. This regression is hard to avoid
and the 30s was chosen to minimize the regression potential while
still giving more than 5s to u-u to finish actions. Bugs reporting
increased delay to sleep or shutdown should be monitored to catch
other programs misbehaving with this new default.
