i wouldn't remove it but just disable the cron jobs for it
in /etc/cron.daily and /etc/cron.weekly. as long as you do not do an LTS
to LTS upgrade just using apt-get dist-upgrade regular will be fine ...
in case you upgrade to a new release you should re-install it to manage
the upgrade for you though ...
