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
