Problem CUDA installation

[Morgotheron]

I get a computer to work. I dont know what people do in that computer. I have account with administrator permissions. I have Ubuntu in version:
kuba@wojtek-Z370-HD3P:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
I have a problem with CUDA installation. I need CUDA for molecular modelling

I install CUDA by this tutorial and this tutorial works on two other computers.

I did these steps:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
gcc -v
make -v

then

lspci | grep -i nvidia
I dont see anything after I wrote this!!!!! I think that there is a problem with that

Only this show me informations
sudo lshw -c video
[sudo] password for kuba:

Then I wrote
gcc --version and it shows me gcc version

Then installation from this site

CUDA Toolkit 12.1 Downloads

Get the latest feature updates to NVIDIA's proprietary compute stack.

developer.nvidia.com

Installation Instructions:

`sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.168-418.67_1.0-1_amd64.deb`
`sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub`
`sudo apt-get update`
`sudo apt-get install cuda`

I have errors installation, but it installed

Then

to bashrc I add
export PATH=/usr/local/cuda-10.1/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64:$LD_LIBRARY_PATH

Then I check CUDA, but its not installed properly
kuba@wojtek-Z370-HD3P:~/samples/1_Utilities/deviceQuery$ ./deviceQuery
./deviceQuery Starting...

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 100
-> no CUDA-capable device is detected
Result = FAIL




I try to uninstall CUDA, but I cant find deinstallation files

1. Introduction — Installation Guide for Linux 12.4 documentation

I try to use purge, but my apt-get dont working
sudo apt-get --purge remove cuda-10.1



You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cuda-libraries-dev-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but it is not going to be installed
cuda-samples-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but it is not going to be installed
cuda-visual-tools-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but it is not going to be installed
nvidia-361 : Depends: nvidia-367 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

But this "apt --fix-broken install" didnt work
