It looks like you have a package libcublas-dev installed, which is not from the Ubuntu archive, and this package does not declare the correct Conflicts relationships with nvidia-cuda-dev, which is in the Ubuntu archive.

You'll need to resolve the conflict manually, i.e. remove one or the other package.
