Unable to access CUDA repo from CUDA L4t docker container

When I run apt update I get this message

Err:1 http://cuda-internal.nvidia.com/release-candidates/kitpicks/cuda-r10-2-tegra/10.2.460/006/repos/ubuntu1804/arm64 InRelease

Could not resolve ‘cuda-internal.nvidia.com

hi jcwscience:
do you set --net=host when run docker? can you run apt update correctly in host?

I am using net host. However I’m running an experimental arch linux build. I was hoping I could use the container to run cuda programs without using the nvidia runtime
