cuda install woes

nvidia driver rabbithole - ‘kernel configuration is invalid’

I have been having some trouble installing an nvidia driver for a K80 gpu on an ubuntu 14.04 headless machine.    I tried several install methods (local .deb, local runfile, remote .deb, apt-get install of nvidia packages, and adding a ppa) and none succesfully allow communication with the gpu.

None of these have succeeded. An example is the following error (from the remote .deb attempt)

I don’t have this problem when installing 352.79 driver(runfile) on my Ubuntu14.04.3_x64/Tesla K80 systems.
Can you post the full information in nvidia-installer.log, it could be generated after driver runfile installation.
