Comment 31 for bug 1796376

Hi Eric,

I confirm that this behaviour can only be reproduced in 'uu' context and only in 'shutdown mode'.

I can also confirm that the upgrade process is now OK in Bionic with your test package :

- unattended-upgrades version after the test package installation :

ii unattended-upgrades 1.1ubuntu1.18.04.6+testpkgb1 all automatic installation of security upgrades

- dpkg status for linux-cloud-tools-common after reboot + 'uu' in 'shutdown mode' :

ii linux-cloud-tools-common 4.15.0-36.39 all Linux kernel version specific cloud tools for version 4.15.0

- APT logs for linux-cloud-tools-common :

Start-Date: 2018-11-02 16:28:56
Commandline: /usr/bin/unattended-upgrade
Upgrade: linux-cloud-tools-common:amd64 (4.15.0-34.37, 4.15.0-36.39)
End-Date: 2018-11-02 16:29:01

Would it also be possible to backport the fix in Xenial, as this version is also impacted ?

Thanks a lot for your help.
