Hi @harshguruofficial143, Ubuntu 22.04 isn’t officially supported on the Jetson Nano, which goes up to JetPack 4 and Ubuntu 18.04. You might be able to find a way, but it’s unlikely that it would work with GPU acceleration.
Instead, I have ROS Humble containers built for JetPack 4 available here:
dustynv/ros:humble-ros-base-l4t-r32.7.1dustynv/ros:humble-ros-core-l4t-r32.7.1dustynv/ros:humble-desktop-l4t-r32.7.1
If preferred, you can use my ros2_build.sh script to compile Humble on your device outside of container.
