I tried to install cuda7 on a new ubuntu 14.04 LTS workstation and received the following error massage.

"
trying to overwrite ‘/etc/OpenCL/vendors/nvidia.icd’, which is also in package nvidia-opencl-icd-331-updates 331.113-0ubuntu0.0.4
Errors were encountered while processing:

Can not correct it with “apt-get -f install”. Please help!

start over with a clean OS install and use the runfile installer method instead of the package manager installer method.

Thanks for the response. There are a number of licensed software packages in the system already and will be really pain-taken to reinstall. Any other way to correct it?

Try using the runfile installer. If you have trouble, review the installer log files.

I have tried runfile installer. It went through smoothly.

However, “apt-get -f install” still gives me the same error as following:

apt-get -f install

We keep receiving warnings from the “package manager” but not able to correct it:-)

Any advice on how to correct it ?

Thanks in advance!

I am having the same issue. Have been struggling with it for over a day now. If you have found a solution, kindly share it here. If not, can you guide me to remove all nvidia packages from Ubuntu, maybe reinstalling Cuda will help.
Thanks in advance!

Found a solution to all this mess.

Ran the following two commands and got my dependencies resolved.

sudo dpkg -P nvidia-opencl-icd-331-updates

sudo apt-get install -f

Restart your system after this.

Thank you @mnoumanshahzad, the above solution solved the issue.

Tried the same thing and now my system says “The system is running in low-graphics mode”, and I can’t get out of that. Any help?
