          You can do this by installing the unattended-upgrades package; see its documentation for details of its configuration.



          sudo apt install unattended-upgrades


          will install it for you.



          Installing it should be sufficient to enable it. To allow it to reboot when necessary, you’ll have to add a configuration file, e.g. /etc/apt/apt.conf.d/52unattended-upgrades-local, containing



          Unattended-Upgrade::Automatic-Reboot "yes";


          By default, on Ubuntu, it will install any upgrade from the main repositories, whether it’s security-related or not. You can configure more repositories if necessary by overriding the Unattended-Upgrade::Allowed-Origins configuration key.

          • How official is this software source? I would not recommend to any user to install something from another source than their OS's software repository. Perhaps Ubuntu has something built-in (like CentOS's yum-cron)?
