Generate a mail listing packages which are pending an upgrade
apticron [--cron]
apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes - using apt-listchanges - to a configurable Email address.
apticron is mainly intended for automatic notification of pending security updates but can also be used in many other situations where timely updates are necessary.
The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.
/etc/apticron/apticron.conf
Custom settings go into this file, such as email and profile for apt-listchanges. You can use /usr/lib/apticron/apticron.conf as a template. The values set in /etc/apticron/apticron.conf will override the default settings in /usr/lib/apticron/apticron.conf.
/etc/cron.d/apticron
Cron job for executing apticron daily.
/var/lib/apticron/cron_run
Time stamp file used by apticron when invoked with --cron option.
