K80 install problem

I have been going crazy the last 3 days trying to install drivers and get my k80 running on Ubuntu 18.04.

Ive tried installing on Ubuntu 20 also with no luck so decided to go to an older version since its an older gpu.

This is what im getting

sfrye@ella:~/Downloads$ nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

sfrye@ella:~/Downloads$ nvidia-settings

ERROR: NVIDIA driver is not loaded
