Hi, The command xhost +si:localuser:root should run on the host, not in the container. Also are you sure you're using the Jetpack 4.2 on your Jetson ? It's now quite old and the version must match exactly to work

Hello, Thanks for the answer. I will try to run xhost +si:localuser:root as noted.

About Jetpack: I just flashed the most recent version of NVIDIA OS following the "getting started guide" https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit

Thanks.

Ok, so you should have JP4.6.1. You should use stereolabs/zed:3.8-devel-jetson-jp4.6.1 or stereolabs/zed:3.7-devel-jetson-jp4.6.1
