There's an issue with an Alpha/Beta Release of Ubuntu, what should I do?

I've been running 12.10 for about a week now with pretty minimal issues so far; the main problem I'm experiencing is that the nvidia drivers I have are refusing to upgrade. I'm currently using the experimental drivers, so I'm not sure if that has anything to do with it. Either way, I was hoping to see if anyone could make any sense of this output:

From apt-get upgrade:

What would be the solution to this? I already tried an apt-get clean along with a apt-get -f upgrade after, and that didn't solve the problem.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

nvidia-settings-updates and nvidia-settings-experimental are two version of the same software, you shouldn't use them both at a time, or you'd get an error as above. Uninstalling one of them should be fine.
