I'm trying to work out the best way to run unattended upgrades every Thursday at 3am but can only see a way to run this weekly but not a given time.
I thought of one way would be to have a script that is called by cron on Thursday at 3am
The below script would work just for security updates
#!/bin/sh sh -c 'grep precise-security /etc/apt/sources.list > /etc/apt/secsrc.list' sh -c 'apt-get -o Dir::Etc::sourcelist="secsrc.list" \ -o Dir::Etc::sourceparts="-" update && \ apt-get --assume-yes upgrade'
Any thoughts on another way?
