Hello, when I run roslaunch rl_navigation roslaunch rl_navigation turtlebot3_stage_1.launch on ubuntu20, the following error is reported, showing that the model cannot be found

roslaunch rl_navigation turtlebot3_stage_1.launch I corrected the command. You should execute the above command.

Sorry, I just typed the wrong command, I executed roslaunch rl_navigation turtlebot3_stage_1.launch, it reports that the model does not exist on ubuntu20, but I run in ubuntu18 without errors, is it a problem with the ubuntu version？

I exectuted the command in Ubuntu20, ros-noetic (ROS1), and it worked well. Maybe you should install the following packages if you are using ros-noetic sudo apt-get install ros-noetic-gazebo-ros-pkgs ros-noetic-gazebo-ros-control

Hello, I had the same problem with ubuntu 20.04, how was it eventually resolved? Thank you very much and looking forward to your replies.
