another way of periodically updating the lists of packages is to add
this line in a file under /etc/apt/apt.conf.d/ e.g.
/etc/apt/apt.conf.d/10periodic:

APT::Periodic::Update-Package-Lists "1";

The update of the package lists will then be triggered once a day by the
script /etc/cron.daily/apt .

If your system is not always up and you have anacron installed, doing it
this way is better than creating a cron job running apt-get update.
Because anacron is responsible for the execution of scripts under
/etc/cron.daily (see /etc/anacrontab), you are assured that the update
is run as soon as your system is up and 24 hours are elapsed since the
last time the scripts under /etc/crond.daily/ were run.
