Package 'turtlebot3_gazebo' not found:

Hi!

I’ve followed the instructions for Simulation

But for this commands:

$ export TURTLEBOT3_MODEL=burger
$ ros2 launch turtlebot3_gazebo empty_world.launch.py

I have this result:
Package ‘turtlebot3_gazebo’ not found: “package ‘turtlebot3_gazebo’ not found, searching: [’/opt/ros/foxy’]”

Please, help!

That error indicates that you are missing some requred dependancies. The virtualization setup also instructs you to complete the full PC setup process for your operationg system. Did this process complete correctly?
