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.

[gazebo-1] process has died [pid 6687, exit code 255, cmd /home/khan/catkin_ws/src/gazebo_ros_pkgs/gazebo_ros/scripts/gzserver -e ode worlds/ __name:=gazebo __log:=/home/khan/.ros/log/d617c55e-a370-11e7-8dfc-572a807118e3/gazebo-1.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.

Please, note that I am using Ubuntu 16.06 with ROS-Kinetic.

I am very thankful to you for your kind suggestions. Thank You.
