Can not get Turtlebot to move to a certain point

I completed the turtlebot turotials but am having a tough time converting it to real life.

I am able to do everything correctly on my turtlebot except that I can not send it to a certain location. I am able to create a map, save it, load it back up, and localize my robot. When launching the RVIZ, I get this error. I have made sure that DWAPlannerROS is installed by doing this command “sudo apt-get install ros-melodic-teb-local-planner” but my problem still persists.

[FATAL] [1644336371.394594454]: Failed to create the dwa_local_planner/DWAPlannerROS planner, are you sure it is properly registered and that the containing library is built?

Hi Grant,

Could you please let us know the specific course you are taking?

I have completed all the python courses with turtlebot. I am trying to get it working on the physical turtlebot now
