Hello, Since few days im trying to set up a Gazebo alongside with ROS, the installation goes smoothly but there are problems when it comes to getting models. They refuse to download and because of that i cant add anything to my world nor open any worlds.

Every time i install Gazebo, no matter how i do it and which version, it gets stuck on:

Warning [ModelDatabase.cc:334] Getting models from[http://gazebosim.org/models/]. This may take a few seconds.
Warning [gazebo.cc:215] Waited 1seconds for namespaces.

This above was from gazebo 2.2 with ROS Indigo, i was suggested to upgrade to newer version to solve this issue but even when i installed Ubuntu 16 LTS with Gazebo 7 and ros Kinetic the issure remained.

For the installation i used methods described in this tutorial wiki.ros.org/kinetic/Installation/Ubuntu and after each install i followed up with steps from this tutorial wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment All the instructions execute flawlessly untill i get to launch Gazebo and every time models fail to download.

I even tried to do a clean install of gazebo with sudo apt install gazebo7 and even then the same issue remains:

Also, the splashscreen is stuck on Preparing your world during that time.

It takes a while to download some assets the first time you load Gazebo, is the computer connected to the internet and did you give it enough time?
