@Frank: Let me get this straight; you were using Ubuntu 8.04, and you upgraded with a Ubuntu Studio 10.04 DVD? I'm afraid that won't work at all, since the Ubuntu Studio DVD doesn't contain all the needed packages for a Ubuntu vanilla system. You should have used the regular Ubuntu Lucid cd for the upgrade.
