image description 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
... logging to /home/ditu1308/.ros/log/31042b82-eb5e-11ea-aa9a-f73278607943/roslaunch-Swastik-VivoBook-14-ASUS-Laptop-X407UAR-9899.log
Checking log directory for disk usage. This may take a while.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.

Resource not found: The following package was not found in <arg name="world_name" value="$(find turtlebot3_gazebo)/worlds/turtlebot3_world.world"/>: turtlebot3_gazebo
ROS path [0]=/opt/ros/noetic/share/ros
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

after you run catkin_make command, you need to source the devel folder. Then the roslaunch command will be able to find the turtlebot3_gazebo package. (I see that this is not mentioned in the website you are following

$source ~/catkin_ws/devel/setup.bash

2.I think this is the official manual for turtlebot3: https://emanual.robotis.com/docs/en/p...
