Description

In the CUDA manual installation instructions, the docs currently suggest:

wget https://developer.download.nvidia.com/compute/cuda/repos/$os/$(uname -m)/cuda-keyring_1.1-1_all.deb

On a Jetson AGX Orin (JetPack 6.0, Ubuntu 22.04), this fails because:

• uname -m returns aarch64
• NVIDIA’s repo does not have an aarch64/ directory (see below for ubuntu2204):

• The correct directory is arm64/ (for ARM systems) or x86_64/ (for PCs)

This causes a 404 when trying to download cuda-keyring_1.1-1_all.deb.

The user could probably figure out how to resolve this. But just in case, I'll try to provide a solution for this error

Expected behavior

Expected behavior:
The documentation should use Debian’s packaging architecture (dpkg --print-architecture) and map it to NVIDIA’s repo naming convention:

• amd64 → x86_64
• aarch64 → arm64

Actual behavior

WGET returns a 404

Notice the aarch64 part in the Nvidia URL which is a non-existent folder.

Steps to reproduce

os=ubuntu2204   # or whatever os you are using
# uname -m will return aarch64 on a Jetson machine, which leads us to a 404
wget https://developer.download.nvidia.com/compute/cuda/repos/$os/$(uname -m)/cuda-keyring_1.1-1_all.deb
