Hi all:
The stable repository packages.osrfoundation.org now hosts the ROS Kinetic and ROS Lunar wrappers binaries for the latest release of Gazebo: gazebo9. Both are only available on Ubuntu Xenial since it is the only common platform supported by ROS and gazebo9.
Before using this alternative version of Gazebo in Lunar or Kinetic, please read carefully the documentation:

Enjoy.
