Hi, I'm trying to run turtlebot3 simulations (https://emanual.robotis.com/docs/en/platform/turtlebot3/simulation/) and I get this error:

$ ros2 launch turtlebot3_gazebo empty_world.launch.py

How to solve?

P.S. I can run gazebo alone smoothly.

Hi @matteoderose Could you try install gazebo packages with the command below?

$ sudo apt-get install ros-foxy-gazebo-*

Many thanks, problem solved. I reinstalled ros2, gazebo (using your suggestion) and turtlebot3 and now it works. Useful video to install everything correctly: https://www.youtube.com/watch?v=8w3xhG1GPdo
