I am using ROS melodic - Ubuntu on Windows

When running the command

$ roslaunch beginner_tutorials turtlemimic.launch

I get the following message

[Not an answer] Sorry if this is not in accordance with ROS ANSWERS common practices. I am ameteur.

I have encountered a similar error with turtlebot3_navigation (other packages like turtlebot3_gazebo work fine). I have run the same launch files days ago, and they worked like a charm. Currently no idea why this happens.

System setup : ubuntu 16.04 on Windows 10 and ros kinetic

Error messages:...

I am trying to resolve this but unsuccessful so far.

Reinstalling turtlebot3 packages (e.g. ros-kinetic-turtlebot3, ros-kinetic-turtlebot3-gazebo ...) eliminated the issue. What is this lol.
