Hey Guys,

I am gotten myself into a real mess, and really need some help. I am currently running ROS Hydro, and I am aware that I need to run Gazebo 1.9.x in order for my ROS simluations to work on Gazebo. I have installed Gazebo 1.9.3 and verified that I have installed it correctly.

Now here is where the problem I think is. I used this command to install ros-gazebo pkgs

sudo apt-get install ros-hydro-gazebo-ros-pkgs ros-hydro-gazebo-ros-control

For every file installed I saw a version number of "2.3.4" in it and example:

Setting up ros-hydro-gazebo-msgs (2.3.4-0precise-20140130-1938-+0000) ...

Is this version number associated with Gazebo 2.x or 1.9.x? Is this correct files for the ROS-Hydro-Gazebo package ?

After successfully installing the ROS-Hydro-Gazebo package, I tested using the gazebo_ros package by using the command

source /opt/ros/hydro/setup.bash

rosrun gazebo_ros gazebo

After running these commands my node gets stuck waiting for the gzserver and finally the command fails.
