This bug was fixed in the package unattended-upgrades -
1.1ubuntu1.18.04.10
---------------
unattended-upgrades (1.1ubuntu1.18.04.10) bionic; urgency=medium
* do_auto_remove() is successful unless a commit() operation fails
(LP: #1795696)
* Compare apt.package.Version objects and not the versions' string
representation. (LP: #1820888)
This prevented adjusting candidates when the strings sorted differently.
Also extend tests to catch issue.
* Fall back to adjusting more packages' candidates
when a package from an allowed origin can't be marked to install/upgrade.
(LP: #1821101)

Bug description:
[Impact]
* Unattended-upgrades crashes while auto-removing kernel packages.
[Test Case]
1. Install kernel packages to be automatically removed:
# eatmydata apt install linux-image-4.18.0-13-generic
linux-image-4.18.0-14-generic linux-image-4.18.0-15-generic
# apt-mark auto linux-image-4.18.0-13-generic linux-image-4.18.0-14-generic
linux-image-4.18.0-15-generic
# /etc/kernel/postinst.d/apt-auto-removal
2. Set up u-u to perform action in non-minimal steps:
# grep Minimal /etc/apt/apt.conf.d/50unattended-upgrades
Unattended-Upgrade::MinimalSteps "false";
3. Run u-u in dry-run mode.
Observe it failing with not fixed versions:
# unattended-upgrade --dry-run
Traceback (most recent call last):
File "/usr/bin/unattended-upgrade", line 1998, in <module>
sys.exit(main(options))
File "/usr/bin/unattended-upgrade", line 1798, in main
options.verbose or options.debug, options.dry_run)
File "/usr/bin/unattended-upgrade", line 1495, in do_auto_remove
if res:
UnboundLocalError: local variable 'res' referenced before assignment
Observe the fixed version running properly:
# ./unattended-upgrade --dry-run
#
[Regression Potential]
* The fix is very small and isolated, but a programming error could
cause the misreporting of the success of auto-removals. Considering
the size and simplicity of the change, regressions here seem unlikely.
