How to launch turtlebot3 in ROS Noetic

edit

I am a beginner in ROS and Linux. I have installed Ubuntu 20.04 and ROS Noetic. The installation was successful. I have also created the catkin workspace. However, I am facing issues while launching the turtlebot3 in gazebo. This is the error the traceback:

~/catkin_ws/src/turtlebot3_simulations/turtlebot3_gazebo/launch$ roslaunch turtlebot3_world.launch

ROS path [1]=/opt/ros/noetic/share
The traceback for the exception was written to the log file

I couldn't find a proper documentation for turtlebot3 installation in noetic in the official documentation page. So I followed the step according to this website:

Please guid me through this. I am getting suggestions to downgrade to a lower version of Ubuntu where I can use ROS Melodic, but I hope there is some other way out. Thank You
