I can't see anything obvious in the sosreport, minus the fact I clearly see the package in "iFR" state.
I asked a colleague of mine to test in Azure to double-check but my KVM guest tests look good so far : # apt-get install linux-cloud-tools-common -y Reading package lists...

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.
