Gazebo Crashing [closed]

edit

I am facing a problem about Gazebo. It crashes when I run the code roslaunch seven_dof_arm_gazebo seven_dof_arm_world.launch of chapter 3 given in the Book "Mastering ROS for Robotics Programming". In particular, I face the following problem.

 spawn_model script started
[gazebo-2] process has died [pid 12409, exit code 255, cmd /opt/ros/kinetic/lib/gazebo_ros/gzserver -e ode worlds/empty.world __name:=gazebo __log:=/home/khan/.ros/log/6dcae69c-763b-11e6-989e-10604b7e1ec1/gazebo-2.log].

I have tried following these solutions (link1, Link2) and I feel that my problem is quite similar to that but as it can be noticed that these problems are not yet resolved there so I cannot go any further. Please, help me out to overcome this problem. It is worth mentioning that I am using Ubuntu 16.06 with ROS-Kinetic. I shall be very thankful to you for your kind suggestions.
