Installing CUDA by rpm file

In the CUDA install website

http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/

my system hangs on the follwing commands.

•Redhat & Fedora

sudo rpm --install cuda-repo-<distro>-<version>.<architecture>.rpm sudo yum clean expire-cache
$ sudo yum install cuda

Actually it is only the last command.

Is there a workaround for this?

Respectfully,
