Hi Guillaume, I seemed to only be able to reproduce the behaviour in the 'uu' context, if for instance I upgrade the pkg using apt, it goes well for me so far.
Can you conclude you are experiencing the same outcome as me and you are only able to fully reproduce when 'uu' is involved ? -- 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.)
