I am following the procedure given here :
http://www.r-tutor.com/gpu-computing/cuda-installation/cuda6.5-ubuntu

However, after I do sudo apt-get install cuda I get the following message:

You might want to run 'apt-get -f install' to correct these:

The following packages have unmet dependencies:

cuda-drivers : Depends: nvidia-opencl-icd-346 (>= 346.46) but it is not going to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

After I enter sudo apt-get -f install I get the following message:

Preparing to unpack .../nvidia-opencl-icd-346_346.46-0ubuntu1_amd64.deb ...

How to do this ?

p.s. sudo apt-get install cuda-runtime-7-0 gives the same error.
