I have this sinking feeling that my system isn't fully upgraded to the released 10.10. If nothing else I am missing the Ubuntu Font Family. It just feels like some things aren't updating. I don't know if from release to release, beta to LTS, there aren't that many updates but I certainly haven't been seeing long lists when I start my update manager.
I just don't feel like I'm upgraded/updated to the LTS 10.10. How can I check? And if not, how can I update?
