this crashed my server..

sudo ln -s /usr/lib/x86_64-linux-gnu/libnccl.so.2 /usr/local/cuda/nccl/lib/

ln: target '/usr/local/cuda/nccl/lib/' is not a directory: No such file or directory

In what point is nvcc installed ?

You can have nvcc by install nvdia cuda toolkit: "sudo apt install nvidia-cuda-toolkit". Now you can check the directory again. good luck

While doing sudo apt install -y cuda=10.0.130-1 I ran into a error: cuda : Depends: cuda-10-0 (>= 10.0.130) but it is not going to be installed. Running sudo dpkg --force-all -i cuda-repo-ubuntu1804_10.0.130-1_amd64.deb fixed it for me. Note, though, that that will overwrite any existing versions.
