Hi @dve_b I was not able to get Noetic building on 22.04, which is not in the ROS1 apt repo (http://packages.ros.org/ros/ubuntu). Even if you are building from source, you need it to install some build tools first.
So instead I tried switching it to ROS2 apt repo (http://packages.ros.org/ros2/ubuntu) just to install the build tools, but it later failed because of some version issue with the catkin python module. I did find this but haven’t had time to try it:
The CUDA 12 packages for Jetson/aarch64 aren’t available for 20.04, so unfortunately there is an incompatibility and I would stay on JetPack 5 if you need Noetic.
