I downloaded and installed an application that uses CUDA 10.
When I run it, it says:
./main: error while loading shared libraries: libcublas.so.10.0: cannot open shared object file: No such file or directory
The documentation said, that it required CUDA 10 and cuDNN. So, I downloaded and installed both. (... Well, actually I installed CUDA 10.1). But none of that helped. I wasn't sure which one to install, so I installed both the dev and the runtime.
And because still that didn't help, I installed the nvidia-cuda-toolkit. I think that's when things really went wrong. The inevitable happened, I broke it.
I wanted to install one more package: i.e. "cuda-libraries", but it gives an unmet dependency error, refering back to the nvidia toolkit that I installed earlier.

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cuda-libraries-10-0 : Depends: cuda-nvrtc-10-0 (>= 10.0.130) but it is not going to be installed
Depends: cuda-nvgraph-10-0 (>= 10.0.130) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Right now, I can't go back nor forth. When I try to uninstall it gives errors.

Also, the broken-fix switch doesn't help.
It tries to install something, then goes in error again.

The following package was automatically installed and is no longer required:
libnvidia-common-390
Use 'sudo apt autoremove' to remove it.
The following additional packages will be installed:
nvidia-cuda-dev
Recommended packages:
libnvcuvid1
The following NEW packages will be installed:
nvidia-cuda-dev

2 packages include the same file and dpkg do not override it without any --force option.
sudo dpkg --configure nvidia-cuda-dev and ` sudo dpkg --configure nvidia-cuda-toolkit`
Then try to remove the package that violate apt. sudo dpkg -P cuda-libraries-10-0 libnvidia-common-390
Next step
sudo dpkg --configure -a && sudo apt -f install
some packages need to upgrade. But only if you receive no error message before.
sudo apt update && sudo apt full-upgrade
