I am trying to create a map with the rosbag file and doing it exactly as mentioned in the tutorial I am running Ububtu 16.04 with ROS Kinetic:

After starting master I am doing:

rosparam set use_sim_time true

Then I am starting :

rosrun gmapping slam_gmapping _base_frame:=base_footprint

And then starting bag file with --clock as parameter then also I am getting error which I am trying to echo the /map_metadata,No messages received and simulated time is active.Is /clock being published?

And for the matter of fact /clock is being published and when I echo the topic its running fine then why am I not getting map or why when I rosbag file there is no diagnostics being published with gmapping node runnning.

The link to the bag file is this https://drive.google.com/file/d/1ZcEL...
