HectorSLAM implementation on Melodic

Hi I am trying to run the tutorial.launch file in hectorSLAM and I’ve hit a roadblock and keep getting the error in the photo attached when I try to run the tutorial.launch, I am running ubuntu 18.04.4 and ros melodic, any help fixing this error would be greatly appreciated.

Hello @johnkinson,

Personally, I’ve never worked with the hector SLAM packages so I cannot help you very much on this one. I highly recommend you to post this question on the ROS Answers forum, since there’s a high probability someone there might have already tried to implement this on Melodic.
