Possible Duplicate:
What is the equivalent terminal command of Update Manager?

I logged in this morning and had a notification of 25 available updates. I ran apt-get update and apt-get upgrade, and now just having finished the upgrade, I immediately get a notification of additional 8 available updates. I guess there's a difference in where apt-get update and the notifications utility get their information from?

Please help me sort this out.

Some updates require more than a simple apt-get upgrade to install, and so you may not have gotten them installed, as they were held back. You can install them by running apt-get dist-upgrade instead.
