I thought that installing NVIDIA RTX A6000 ADA in default Ubuntu 22 server installation would be an easy one. However, installing drivers from the repository made no good. I verified if secure boot is enable and no it was disabled. We need to install few things first: We need to get rig of previously installed drivers: Verify if secure boot is disabled: Get NVIDIA driver, such as NVIDIA-Linux-x86_64-535.216.01.run from their webiste and install it: In case you got rid of previously installed drivers, disabled secure boot and installed build tools, kernel headers… you will be good to go to compile
