NAME¶unattended-upgrade - automatic installation of security (and other) upgrades
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 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
- detailed APT/LibAPT output for debugging
- -v, --verbose
- show verbose output
- Just simulate installing updates, do not actually do it
- perform upgrade in minimal steps (cancel with SIGINT). This is the default now.
- 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
