You start with the line above: > Loaded: loaded (/lib/systemd/system/apt-daily.timer; … and check the service it provides: $ tail -n 3 /lib/systemd/system/apt-daily.service ExecStartPre=-/usr/lib/apt/apt-helper wait-online ExecStart=/usr/lib/apt/apt.systemd.daily update $ So look at: $ head -n 6 /usr/lib/apt/apt.systemd.daily #!/bin/sh #set -e # # This file understands the following apt configuration variables: # Values here are the default. # Create /etc/apt/apt.conf.d/10periodic file to set your preference. $ That file contains helpful comments and the scripts, but what runs depends on /etc/apt/apt.conf.d/10periodic, or other apt configurations, which I don't have set. Presumably the installers "unattended upgrades" option plays with this stuff. (The heads and tails above are just to trim the post; you're not expected to use them a priori.) Cheers, David.
