Hello everyone,

I just install ubuntu 16.04 and ROS-Kinetic branch .

I installed ros-kinetic-gazebo-ros-pkgs, gazebo7 and all respective dependencies at Synaptic, then I type gazebo at the terminal but nothing has appeared, nothing has happened.Then I type gzserver and the same scenario has been happened again. I tried gzclient I got the Conflicting gazebo versions message at the terminal.

Then I tried "roslaunch gazeboros emptyworld.launch" and I got this at the terminal ,

core service [/rosout] found

process[gazebo-1]: started with pid [15758]

process[gazebo_gui-2]: started with pid [15765]

[gazebo-1] process has died [pid 15758, exit code 255, cmd /opt/ros/kinetic/lib/gazeboros/gzserver -e ode worlds/empty.world _name:=gazebo __log:=/home/delnia/.ros/log/ae0a1190-b53a-11e6-bf65-94dbc9b1a0c0/gazebo-1.log].
