<H2>DESCRIPTION</H2>
|
|
|
|
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
|
|
<P>
|
|
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).
