Hi @xjtu19, this project is currently not maintained, however I think your error could be solved by using the last binaries insted of the source packages in my repo.
Try this:

rm -rf Universal_Robots-*  ur_*  # remove the UR source package
sudo apt-get install ros-humble-ur* # install latest binary of universal robots

You should probably do the same also for ros2_control

rm -rf ros_control*  # remove ros2 control source package
sudo apt-get install ros-humble-ros2-control # install latest binary of ros2 control

If you have problems with gazebo do the same by using the latest source package (I did not find the binary installable with apt)
