Hi all:
The stable repository packages.osrfoundation.org hosts the ROS Kinetic wrappers binaries for the latest release of Gazebo: gazebo8.
Note that they are only available on Ubuntu Xenial since it is the only common platform supported by ROS and Gazebo8.
Before using this allternative version of Gazebo in Kinetic, please read carefully the documentation:

Enjoy.
