#### Install CUDA driver on Ubuntu with Secure Boot enabled

With Secure Boot enabled, all Linux kernel modules are required to be signed by the key trusted by the system.

1. Install pre-built Azure Linux kernel based NVIDIA modules and CUDA drivers
50+
Ubuntu packages NVIDIA proprietary drivers. Those drivers come directly from NVIDIA and are simply packaged by Ubuntu so that they can be automatically managed by the system. Downloading and installing drivers from another source can lead to a broken system. Moreover, installing third-party drivers requires extra-steps on VMs with TrustedLaunch and Secure Boot enabled. They require the user to add a new Machine Owner Key for the system to boot. Drivers from Ubuntu are signed by Canonical and will work with Secure Boot.
