apticron - Generate a mail listing packages which are pending an upgrade

       Apticron  was  initially  developed by Colm MacCarthaigh <colm.maccarthaigh@heanet.ie> with contributions
       from Marc Sherman <msherman@projectile.ca>. Since 2006 it is maintained and improved by Tiago  Bortoletto
       Vaz <tiago@debian.org>.

       In a particular situation apticron may report non-installed packages to be upgraded.  It's  inconvenient,
       but it's not a bug in apticron itself. Please see https://bugs.debian.org/544481#105 for details.

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.
