Installed CUDA 11.2, all samples missing


I have installed the CUDA toolkit 11.2. However, in /usr/local/cuda-11.2 there’s no samples directory and in /usr/local/cuda-11.2/bin there’s no .

Any ideas of what to do to get them and test the installation ?
Other files seem to be there. For example, nvcc -V works

I have Kubuntu 18.04


I discovered that there’s an help option :
sudo sh – help

From that you can just install the samples :
sudo sh – samples
