unattended-upgrade [options]

       This program can download and install security  upgrades  automatically
       and  unattended,  taking care to only install packages from the config-
       ured APT source, and checking for dpkg prompts about configuration file
       changes. All output is logged to /var/log/unattended-upgrades/*.log.

       This  script  is  the backend for the APT::Periodic::Unattended-Upgrade
       option and designed to be run from cron (e.g. via /etc/cron.daily/apt).

       unattended-upgrade accepts the following options:

       -h, --help
              help output

       -d, --debug
              extra debug output into /var/log/unattended-upgrades.log

              Just simulate installing updates, do not actually do it

       The configuration is done via  the  apt  configuration  mechanism.  The
       default  configuration file can be found at /etc/apt/apt.conf.d/50unat-
