Help with updating/installing Nvidia drivers?

Been trying to update my drivers to nvidia 570, but no matter what I try, it never actually installs. I've tried through the pop shop, through sudo ubuntu-drivers autoinstall in the terminal, through the system76 driver install command in the terminal, but nothing; it looks like it starts, but all that results in no DP output from my PC, even after waiting 15+ minutes. Force rebooting after this happens results in the PC booting with no GUI, only a terminal. I'm at my wit's end here; nothing I do seems to work, and the only driver that actually functions is nvidia 470. Can anyone help me figure out what's going on?

edit: for reference, when I run sudo apt install nvidia-570 in the terminal, the process runs, then I get a wall of libkmod: ERROR ../libkmod/libkmod-config.c:772 conf_files_filter_out: Directories inside directories are not supported: /etc/modprobe.d/sound.conf until the process finally resumes, ending with the statement "errors were encountered while processing: nvidia-dkms-570, nvidia-driver-570, system76-driver-nvidia" and the error E: sub-process /usr/bin/dpkg returned with error code (1).

From there, I try running `sudo dpkg --configure -a', but that runs into the same issue: wall of the libkmod error, then errors while processing those three drivers. Then I try 'sudo apt install -f' which results in the exact same errors.

I have a GeForce GTX 1070 graphics card if that helps. sudo ububtu-drivers devices returns nvidia 570 as the recommended one.
