Comment 5 for bug 47533

I have the same problem after upgrade from dapper beta to dapper release : The update notifier doesn't show up anymore. The update notifier daemon is running and I can still hear the hard disk activity that usually precedes the update-notifier pop-up, but it doen't show.
If I manually launch the update manager and check for updates, there are usually some updates available that I was not notified of.

PS : My permissions for sources.list are 644 root root
