So I had successfully install Cuda 7.5. Turns out I needed something pre 6.5, and I was having difficulty installing it.
Seemed like no matter what i did it stayed there, so I did a good search for cuda7.5 using "find" --- and found something like "cuda-repo" in /etc/apt/sources.list.d and erased them (without making backups)
Since then, I've tried installing everything again, but to no avail.
Thinking it was a broken package, I've tried everything from
sudo dpkg --remove --force-remove-reinstreq cuda-repo-ubuntu1404
to plenty of other posts like
http://askubuntu.com/questions/650692/installing-cuda-7-0-on-ubuntu-14-04
and
http://ubuntuforums.org/showthread.php?t=947124
To no avail.
After doing
sudo dpkg -i cuda-repo-ubuntu1404_6.5-14_amd64.deb
and
sudo apt-get update
I get
sudo apt-get install cuda

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-7-5 (= 7.5-18) but it is not going to be installed
libcogl15 : Depends: libegl1-mesa-drivers
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
going down the chain of dependencies manually gets me nowhere-- I went all the way down the chain and simply got to the point where it gave the same error, asking for decencies i had already added to the list! (circular dependency, if you will)
It's also very strange that 6.5 would appear to depend on 7.5
Help? I want to install cuda 6.5!
