I was working with CUDA5.5, however I wanted to install CUDA6.5 using the main repository given by nvidia.
sudo dpkg -i cuda-repo-ubuntu1404_6.5-14_amd64.deb sudo apt-get update
But when I try to install cuda I get the following error.
sudo apt-get install cuda Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: cuda : Depends: cuda-6-5 (= 6.5-14) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
I would appreciate any help.
