Are those nvidia packages held by some APT setting, like apt-mark hold?
You also have WineHQ and Nvidia sources, which will be disabled during the release upgrade but you should consider backing up the configs of their packages and purge the whole lot. There was another topic about some Wine issue, which seemed to be related to a release upgrade from a state with wine from WineHQ which ended up with a Frankenwine from Ubuntu but with config from the previous WineHQ installation, as it seems.
