Comment 10 for bug 2023598

@ahasenack The system with the unattended-upgrade failure was only logged in the apt history.log. It was recorded as "Sub-process /usr/bin/dpkg returned an error code (1)". On another of our systems that didn't have issues, unattended-upgrades updated sssd-common without errors and on a subsequent unattended-upgrade run, about a minute later, it updated libsss-certmap0 successfully. This leads me to believe the one that ran into errors during sssd-common update likely had some other issue with the apt install process unrelated to the out of order update dependency issue but that left libsss-certmap0 in an incompatible state which prevented the system from booting.
