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, taking care to only install packages from the configured APT source, and check‐ ing for dpkg prompts about configuration file changes. All operations are logged to /var/log/unattended-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). OPTIONS unattended-upgrade accepts the following options: -h, --help help output -d, --debug extra debug output into /var/log/unattended-upgrades/unattended-upgrades.log --apt-debug detailed APT/LibAPT output for debugging -v, --verbose show verbose output --dry-run Just simulate installing updates, do not actually do it --minimal-upgrade-steps perform upgrade in minimal steps (cancel with SIGINT). This is the default now. --no-minimal-upgrade-steps do not perform upgrade in minimal steps 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 AUTHORS unattended-upgrade is written by Michael Vogt <mvo@ubuntu.com> This manual page was originally written by Michael Vogt <mvo@ubuntu.com> COPYRIGHT Copyright (C) 2005-2009 Canonical There is NO warranty.
