DESCRIPTIONThis 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).
OPTIONSunattended-upgrade accepts the following options:
- -h, --help
- help output
- -d, --debug
- extra debug output into /var/log/unattended-upgrades.log
- Just simulate installing updates, do not actually do it
CONFIGURATIONThe configuration is done via the apt configuration mechanism. The default configuration file can be found at /etc/apt/apt.conf.d/50unattended-upgrades
