I want to install CUDA 8.0, but I got CUDA 7.5 when using the Nvidia provided *.deb file instead of the *.run installer.
I followed the instructions to install on the Nvidia website:
https://developer.nvidia.com/cuda-80-ga2-download-archive
I installed:
./cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb
Instructions listed on website:
`sudo dpkg -i cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64.deb`
`sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub`
`sudo apt-get update`
`sudo apt-get install cuda`
I performed the "Verify CUDA Installation" step from this answer: https://askubuntu.com/a/799185
Results of running nvcc --version:
$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17
Results from when I run the installer step a second time:
$ sudo apt install cuda
[sudo] password for USER:

cuda is already the newest version (8.0.61-1).
The following packages were automatically installed and are no longer required:
linux-headers-4.13.0-36 linux-headers-4.13.0-36-generic linux-image-4.13.0-36-generic
linux-image-extra-4.13.0-36-generic
Use 'sudo apt autoremove' to remove them.

Definitely Something is incorrect because when I use the *.run version of the installer from the same page, it gives me the following nvcc output:
$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation

Both machines have the same Nvidia Drivers installed:
$ nvidia-smi

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 384.130 Driver Version: 384.130 |
|-------------------------------+----------------------+----------------------+
But the GPU's are different which should not matter because the machine giving issues has a newer graphics card in it. Nvidia GeForce GTX 1050 Ti versus 960M
To avoid conflicts and trouble with finding compatible drivers with Ubuntu 16.04, I just used the additional drivers tab on software-properties-gtk
