To Reproduce Build an image with Ros1 noetic in Scarthgap. This will include python 3.12. This version of python deprecates distutils, which causes problems for some packages. rosclean in the above example. Simply boot the image and run roscore.

Upon patching for distutils, we hit this error as well: https://github.com/ros/ros_comm/pull/2297

Expected behavior We can patch these package by package, but I am puzzled as to why this has not been reported before. Has the combination of Scarthgap and Noetic been tested?

Note we will supply patches for the things we encounter, I just wanted to make sure nothing was missing from my configuration.
