Hi there, I'm new in ROS, i installed ROS-meloidic and working on wander robot, for that i need turtlebot simulator. i have downloaded the turtlebot3 by following command:

sudo apt-get install ros-melodic-turtlebot3-gazebo

and when i run roslaunch turtlebot3_gazebo turtlebot3_world.launch to run the turtlebot3 simulator, i get the following error:

Resource not found: turtlebot3_description

ROS path [1]=/home/kamal/wanderbot_ws/src
ROS path [2]=/home/kamal/catkin_ws/src

This error happens because the package turtlebot3_gazebo fails to declare a dependency on turtlebot3_description but cannot run without it.

You should be able to fix it by installing ros-melodic-turtlebot3-description

There is an open PR to fix it
