Turtlebot launch crashing gazebo

edit

I installed a docker container with gazebo

source: https://github.com/osrf/docker_images...

After this i installed ros kinetic on the container. I want to launch robots ( turtlebot in this case ) so they go in gazebo.

When i run roslaunch turtlebot_gazebo turtlebot_world.launch i get the next error.

[gazebo-2] process has died [pid 21045, exit code 255, cmd /opt/ros/kinetic/lib/gazebo_ros/gzserver -e ode /opt/ros/kinetic/share/turtlebot_gazebo/worlds/playground.world __name:=gazebo __log:=/root/.ros/log/e3d818a2-db5f-11e7-b4d8-0242ac110002/gazebo-2.log].

Any help on how to fix this is really appreciated
