Ok, I´ve created this topic separately, because it´s an Ubuntu issue, so maybe there will be more people with the same bug, so they can find it easier.
I was searching for it and found this (probably solution) on devtalk:
https://devtalk.nvidia.com/default/topic/1048021/error-depends-libcublas-dev-gt-10-1-0-105-but-it-is-not-installed-ubuntu-18-04/
Please, if you guys made a successful install of Cuda Toolkit on Ubuntu and you went through this issues, please draw some tips on how to solve it correctly.

Here is the part from my Ubuntu terminal:
Preparing to unpack …/86-nvidia-prime_0.8.8.2_all.deb …
Unpacking nvidia-prime (0.8.8.2) …
Errors were encountered while processing:

following the last tip from devtalk :
sudo dpkg -i --force-overwrite /var/cache/apt/archives/nvidia-418_418.39-0ubuntu1_amd64.deb

it gives me this :
