On my side I just changed my crontab :

apt-get update && touch /var/lib/apt/lists/lock

so if the update is succesfull, the mtime of /var/lib/apt/lists/lock is
changed, and the apt plugin reports green.
Ah, looks like using a lock file doesn't update the mtime. I didn't
notice until now as I'm using the "all-included" hack suggested in
apt.pl:

44 */4	* * *	root  ! apt-get -qq update 2>&1 | grep -q . && date -u > /var/lib/apt/update_success

Unfortunately apt-get update even returns 0 in case of some errors
(iirc unknown apt-keys etc.), so this command checks for an empty
output of apt-get -qq update instead.
