This script is coming from apt package and is checking every day if
updates are available.

If you want to get automatic updates, there is a tool designed for that
(no need to script by yourself) : cron-apt (which is in Universe). By
default, it only downloads and does not install. Be carefull, automatic
updates on server can be dangerous !
