unattended-upgrade(8)                System Manager's Manual                unattended-upgrade(8)

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, tak-
       ing care to only install packages from the configured APT source, and  checking  for  dpkg
       prompts  about  configuration  file  changes.  All operations are logged to /var/log/unat-
       tended-upgrades/unattended-upgrades.log and the package manager (dpkg) output is logged to
       /var/log/unattended-upgrades/unattended-upgrades-dpkg.log

       This  script  is the backend for the APT::Periodic::Unattended-Upgrade option and designed
       to be run periodically by APT's systemd service (apt-daily-upgrade.service) or  from  cron
       (e.g. via /etc/cron.daily/apt).

       unattended-upgrade accepts the following options:

       -h, --help
              help output

       -d, --debug

       -v, --verbose

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