In coordination with Scott, we have raised this to be a FFe since the package is severity damaged as it is now and probably unusable for any use case that is not completely trivial.
I've created and linked the merge-request with the bumped version against ubuntu/devel and testing the package. ** Description changed: + Patch version to solve a critical problem with colcon argument parsing + mechanism. + + * Merge request: https://code.launchpad.net/~j-rivero/ubuntu/+source/ros2-colcon-core/+git/ros2-colcon-core/+merge/464037 + * PPA related: https://code.launchpad.net/~j-rivero/+archive/ubuntu/noble-pkgs + + + [Justification] + + Recent changes to Python which have been backported to Python 3.11 and + 3.12 break colcon argument parsing due to a dependency on private API in + argparse.
