Hello. I'm trying to launch Kuka youbut from this link So, I run the command: git clone https://github.com/ctruillet/youbot_description.git then I extract the folder and I rename it from youbotdescription-main to youbotdescription I followed the steps that gives me: cd youbotdescription colcon build export GAZEBOMODEL_PATH=$PWD/sdf

but when I run the command: ros2 launch youbot_description gazebo.launch.py

I get this message and gazebo does not open.What should I do?

Ros 2 Humble on Ubuntu 20 Gazebo 11
