NAME

       unattended-upgrade - automatic installation of security (and other) upgrades

SYNOPSIS

       unattended-upgrade [options]

DESCRIPTION

       This program can download and install security upgrades automatically and unattended, taking care to only
       install  packages  from the configured 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).

OPTIONS

       unattended-upgrade accepts the following options:

       -h, --help
              help output

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

       --dry-run
              Just simulate installing updates, do not actually do it

CONFIGURATION

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