I managed to also get it working. Im not exactly sure how but in the process of messing it around i think I've possibly removed a pip package that may have caused the trouble. `pip3 check` still complains with the aformentioned messages but it works. I don't know why the `nbclient` version is no longer a dealbreaker though.

EDIT:
I've found the conflict. the package `yt` installed via `pip install yt` is what breaks it. Not sure whether this should be treated as a problem with `yt` or whether void's jupyter dependencies are just very outdated. For now I will just install both via `pip` since I need both working.
