Hi, The proposed systemd unit change would break :
Unattended-Upgrade::InstallOnShutdown "true"; as the network is no longer available to fetch the archive. As outlined in the systemd documentation : "Given two units with any ordering dependency between them, if one unit is shut down and the other is started up, the shutdown is ordered before the start-up. It doesn't matter if the ordering dependency is After= or Before=." In that context, the network needs to remain available until completion of unattended-upgrade.service. I'm still looking for a combination that will work in all cases. Kind regards, ...Louis -- Louis Bouchard Software engineer, Cloud & Sustaining eng.
