I have setup automatic updates and it updates automatically. However, there are updates that require a restart and I know
Unattended-Upgrade::Automatic-Reboot "true";
will set it to reboot. But it reboots as soon as it updates. That could be at any time of the day, when my users are using my server. I want it to restart at a specific time, say 12:00 am that night. How do I do that?
