[Test Case] * Set up a system with packages (> 30) to be upgraded. In case of Bionic -security has a low number of updates, thus set up the system to install -updates to have more packages for u-u to upgrade: echo 'Unattended-Upgrade::Allowed-Origins:: "${distro_id}:${distro_codename}-updates";' > /etc/apt/apt.conf.d/51-updates * Set up two shells to run commands in parallel * In shell "A" run sudo apt update && sudo unattended-upgrade --dry-run --verbose --debug * After u-u started run the following command in shell "B": while sleep 1; do python3 -c 'import apt; import apt_pkg; print(apt_pkg.pkgsystem_lock())' ; done * Observe the following exception repeated while running u-u and True being printed after u-u is finished: ...

True True True True ... [Regression Potential WIP] * Unattended-upgrade may crash [Other Info] It looks like python-apt also releases the lock sometimes unexpectedly thus the both packages need to be fixed to avoid loosing the lock.
