Hi,
Please noted that docker is pre-included in the JetPack software.
You don’t need to install it manually.
We have double-checked the docker run command on JetPack4.5.1, and it can works correctly.
Could you try the same command to see if it also works?
$ sudo docker run -it --rm --net=host --runtime nvidia -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/l4t-base:r32.5.0
