Using the repository
2. Download the required repositories and install package dependencies:
cd $COLCON_WS git clone -b ros2 https://github.com/UniversalRobots/Universal_Robots_ROS2_Ignition_Simulation.git src/ur_simulation_gz rosdep update && rosdep install --ignore-src --from-paths src -y

The downloaded repository does not match the name of this repository.

This isn't necessarily a problem, since this was the repo's old name and GitHub as a redirection for that. It might be good to update this, nevertheless. Thanks for pointing that out.
