I just inherited a laptop with a broken cuda install and am trying to deal with it without wiping and reinstalling ubuntu20.

Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cuda-libraries-dev-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
cuda-samples-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
cuda-visual-tools-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
and then

all to no avail. The software updates gui says nvidia-driver-440 is in use, any help appreciated. I'd be fine with a working dpkg and no nvidia at all for starters.
