Hi, By setting the JACKAL_LASER_3D to 1 in accesories.urdf.xacro file, Im trying to run ros2 launch jackal_gazebo jackal_world.launch.py with velodyne 3D lidar in the terminal but i get this complicated error, someone else had the same issue here but the answaer which was the lack of velodyne_description package doesnt apply to me because i have that package installed:

Hi, Foxy is EOL and I would suggest moving to Humble. Our docs for that are here: https://docs.clearpathrobotics.com/docs/ros/

Ther is no humble distro for jackal_gazebo:(

That is expected, it is now here: https://github.com/clearpathrobotics/clearpath_simulator for Humble. Check the tutorials.

Thanks, but can you tell me what can be wrong with the code here? Right now i cant change my os or use docker.
