Hi I make a autonomous differential robot. In kinetic devel navigation stack works fine. Robot can get position, goes goal, escape obstacle....However i upgrade my linux and ros base to melodic devel.

In melodic devel i get the error. My robot doesn't avoid from obstacles.I cant solve this... Is there any solution?

I solved the problem. In laser scanner package, frame name is "/laser"... I ommit the "/" then it works

I have the same issue. Could you please elaborate a little bit more on this. I get issues while I'm trying to run the TEB local planner.
