@Eric : The server was installed with a 4.15.0-34.37 kernel from a corporate OS image, and linux-cloud-tools-common package was also in version 4.15.0-34.37. All packages where in state "ii".
I dist-upgrade the server with APT (to version 4.15.0-36.39) and only downgrade the linux-cloud-tools-common package in order to only let unattended-upgrades try to upgrade the linux-cloud-tools-common package and have simpler unattended-upgrades logs to analyze. Upgrading the linux-cloud-tools-common simultaneously with the other kernel packages leeds to the same result. Also, all packages where in state "ii" before running unattended- upgrades. Let me know if you want me to delete the server and deploy it once more with another "fresh" test case. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1796376 Title: Bug #1739107 fix causes linux-cloud-tools-common not to be upgradable with unattended-upgrades on shutdown mode Status in linux package in Ubuntu: Confirmed Bug description: Since the following linux-cloud-tools-common package versions : Xenial : 4.4.0-135.161 Bionic : 4.15.0-34.37 the Systemd service unit file for hv-kvp-daemon has been modified with new dependencies that make the package unable to be upgraded with unattended-upgrades on shutdown mode. Unattended-upgrades hangs with the linux-cloud-tools-common package during "Preparing to unpack". The server restarts after the unattended-upgrades service timeout expires. - Package state after reboot : iFR linux-cloud-tools-common 4.15.0-34.37 all Linux kernel version specific cloud tools for version 4.15.0 - Unattended-upgrades dpkg logs : Log started: 2018-10-05 17:59:04 (Reading database ... 52043 files and directories currently installed.)

Log ended: 2018-10-05 18:00:54 - Impact : The current impact is very important as all security updates are blocked until you manually fix each server with : dpkg --configure -a apt install --only-upgrade linux-cloud-tools-common - Workaround/Fix : As a simple straightforward fix, replacing : Before=shutdown.target cloud-init-local.service walinuxagent.service with : Before=shutdown.target walinuxagent.service makes the package upgradable during shutdown.
