while the Firefox updated successfully and all updates updated successfully? how to I remove this message?

There's no oneiric repository there, it only goes up to natty.

Run
gksu software-properties-gtk and remove the PPA under the Other Software tab.

If your internet connection is running fine, it might be a problem with the repository. Go into Software Sources and look around. If you have added any manual repositories try disabling them. They might not be online any more.
