This question already has an answer here:
I was previous a Kubuntu user but installed ubuntu 12.04 LTS for a week now and I always need to open update manager manually and search. If they're are any updates,because I don't get any notifications, I tried reinstalling update-manager and update-notifier and still no updates notifications.
On Kubuntu I always received update notifications after most 1 minute after i start my pc.
Why is that and how can i fix it?
