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

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.
