Setting cron-apt

First install it.

apt-get install cron-apt

I like to get e-mail every time the cron-apt runs. This way I know that everything works. To get the mail change MAILON=”error” to MAILON=”always” and uncomment the line in /etc/cron/apt/config.

Reconfigure exim4

dpkg-reconfigure exim4-config
