Are ROS Gazebo installers broken? Each time fails to load models.

edit

Were they ever updated, because it feels like they are old and broken.

For last few days im trying to come up with a fail-proof seamless method of installing ROS and gazebo with turtlebot. Each time im stuck at the same step, after sucessfull installation and everything,i launch gazebo (either simply gazebo or roslaunch turtlebot_gazebo turtlebot_world.launch) and gazebo gets stuck at:

Warning [ModelDatabase.cc:334] Getting models from[http://gazebosim.org/models/]. This may take a few seconds.

In result the whole world loads empty and i cant place any models in it because library is empty.

At first i was trying with Ubuntu 14 and ROS Indigo. Then i updated to Ubuntu 16 and ROS Kinetic. The issue is still present. Im using this tutorial step by step (of course for indigo i use indigo version and for kinetic i use kinetic) http://wiki.ros.org/kinetic/Installat... and i also follow steps from this part http://wiki.ros.org/ROS/Tutorials/Ins...

Everything checks out exactly as described untill i try to launch gazebo...

Ive seen this topic, not a single solution from there helped me, https://answers.ros.org/question/1994... , downloading models manually is not an option.
