Getting Started Errors Ubuntu 24.04

[MichaelrMentele]

Description

Failing to get through the build step of the moveit2 tutorial https://moveit.picknik.ai/main/doc/tutorials/getting_started/getting_started.html#install-ros-2-and-colcon

Your environment

• ROS Distro: Jazzy
• OS Version: Ubuntu 24.04
• Source or Binary build? Source, from tutorial
• If binary, which release version?
• If source, which git commit or tag?
  Moveit2: 1d93035fc4fbc2831916bce26d7b03e15b8a86d5
  Tutorials: b05445a

Steps to reproduce

I'm just following along the tutorial here https://moveit.picknik.ai/main/doc/tutorials/getting_started/getting_started.html#install-ros-2-and-colcon

When I try to colcon build --mixin release, I first get errors about catkin_pkg not being found to import. After pip installing catkin pip install catkin_pkg (seems like it shouldn't be needed anymore) I get a different error with moveit_msgs

I attached my notes stepping thru each step as markdown using warp terminal.

Expected behaviour

The build should complete successfully. I do recognize I'm on Ubuntu 24.04 and using the latest Ros2 build but it seems worth logging as an issue for those targets. I'll attempt to work around this by using a docker container to work with move it.

This is an issue with the Python packages configured locally on your end -- see e.g. here: ros/genmsg#63

Given you're on Ubuntu 24.04, and if you don't want to use a virtual environment to do pip installs, you could consider trying sudo apt install ros-dev-tools as shown here: https://docs.ros.org/en/jazzy/Installation/Ubuntu-Install-Debians.html#install-development-tools-optional

[MichaelrMentele]

Thanks for the clue @sea-bass. I'll try rebuilding my virtual env with python.

I pasted a link wrong in my previous comment. Updated.
