Determining the current configuration
The current configuration can be queried by running:
apt-config dump APT::Periodic::Unattended-Upgrade
Which will produce output like:
APT::Periodic::Unattended-Upgrade "1";
In this example, Unattended Upgrade will run every 1 day. If the number is "0" then unattended upgrades are disabled.
The files in /etc/apt/apt.conf.d/ are evaluated in lexicographical order with each file capable of overriding values set in earlier files. This makes it insufficient to view the setting in /etc/apt/apt.conf.d/20auto-upgrades and why it is recommended to use apt-config.
