No camera message received with tum_simulator

edit

I am running tum_simulator in ros kinetic ubuntu 16.04 when i run $ roslaunch cvg_sim_gazebo ardrone_testworld.launch

i get the following warning,

and when I $ rostopic echo /ardrone/front/camera_info

WARNING: no messages received and simulated time is active.
Is /clock being published?

I get the above message.

Is it because the camera xacro is not loaded properly? I did not have such issues while running with ros indigo. I get this issue after I moved to kinetic and gazebo7.14

How do i resolve this?

UPDATE:

I was trying to run tum_ardrone with tum_simulator and the drone camera feed window in tum_ardrone did not open. When I searched for possible reasons, I found that without the camera topic, the drone camera feed window will not open.

And when I checked the camera topic published by tum_simulator, there were no messages.

The output of, $ rostopic list

when i check for the camera topic info, it shows there are no publishers. $ rostopic info /ardrone/front/image_raw

Type: sensor_msgs/Image

Publishers: None

Subscribers: 
 * /gazebo (http://dyana-Inspiron-3542:35595/)

I wonder why? while working with indigo I was launching the same launch files, $ roslaunch cvg_sim_gazebo ardrone_testworld.launch with $ roslaunch tum_ardrone tum_ardrone.launch and I would get drone camera feed opened by tum_ardrone

Also when launching tum_simulator for the first time, i got the following error,
