Mismatched CUDA architecture during SDK installation

Hello,
I am attempting to install the Jetson SDK components to my Xavier but am getting the following error. My host computer is an Intel NUC Hades. I am attempting to install (the older) JetPack 4.2 because it is compatible with the Intel RealSense patch which I will plan to apply later on.

08:51:18 INFO : CUDA Toolkit for L4T : *begin sudo dpkg -i /opt/nvidia/deb_repos/cuda-repo-l4t-10-0-local-10.0.166_1.0-1_arm64.deb, 5

08:51:18 INFO : CUDA Toolkit for L4T : package architecture (arm64) does not match system (amd64)

Something in the install steps is wrong…not quite sure what. The gist is that the arm64 package is correct for the Jetson, but you’re trying to install it to the host PC (amd64). You might see what happens if you manually copy “cuda-repo-l4t-10-0-local-10.0.166_1.0-1_arm64.deb” to the Xavier (e.g., with scp), and then from the location of that file run:

sudo dpkg -i ./cuda-repo-l4t-10-0-local-10.0.166_1.0-1_arm64.deb
