How to solve conflict with libnvidia-nscq 510 and 515?

I am using Xubuntu 22.04 with the Nvidia 515 drivers including the CUDA toolkit and all that comes with it as dependencies (using it for PyTorch and TensorFlow).

I went on a vacation and now that I am back I wanted to install Evince (need a non-browser based simple PDF viewer). Instead of a speedy installation I got this:

Reading package lists... Done Building dependency tree... Done Reading state information... Done You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: libnvidia-nscq-510 : Depends: libnvidia-nscq-515 but it is not installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I checked and I don't have any NSCQ installed (which has something to do with GPU computing in server nodes from Nvidia).

I tried fix-broken. Before that I cleaned it by doing apt-get clean and pulled an updated package list via apt-get update. I also tried apt-get upgrade`.

I am afraid that, if I were to remove CUDA and the Nvidia drivers, I will render my computer unfit for duty (machine learning).

Using dkms status I got

nvidia/515.86.01, 5.15.0-53-generic, x86_64: installed

Also using dpkg -l *nvidia* I tried retrieving some info on the NSCQ package:

While my initial goal (installing a PDF viewer) can be postponed, this mess prevents me from installing anything.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
