unattended-upgrade - automatic installation of security (and other) upgrades
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).
unattended-upgrade accepts the following options:
- -h, --help
- help output
- -d, --debug
- extra debug output into
- Just simulate installing updates, do not actually do
The configuration is done via the apt configuration mechanism. The default
configuration file can be found at /etc/apt/apt.conf.d/50unattended-upgrades
