Code:

cd Downloads/
tar xzf l_opencl_p_18.1.0.015.tgz
cd l_opencl_p_18.1.0.015/

sudo ./install.sh

The installer will tell you if you have installed all the packages that are needed (prerequisites), otherwise you will get an error or warning.

You can actually ignore the too new Ubuntu version or similar warnings, in most of the cases it will work anyway.

but the other requirements are of course needed like build tools etc (build-essential, gcc, and some libs)
