# Revision history [back]

I know this question has been asked before, but seeing as there is a web server involved, those older questions (and their answers) might not be applicable any more, so here is a new one.

While starting a fresh install of Gazebo 7 (with ROS Kinetic, but I'm not sure that is relevant here) with gzserver --verbose the only output produced is:

Gazebo multi-robot simulator, version 7.0.0
Copyright (C) 2012-2016 Open Source Robotics Foundation.

http://gazebosim.org

[Msg] Waiting for master.
[Msg] Connected to gazebo master @ http://127.0.0.1:11345
[Err] [RenderEngine.cc:699] Can't open display:
[Wrn] [RenderEngine.cc:97] Unable to create X window. Rendering will be disabled
[Wrn] [RenderEngine.cc:301] Cannot initialize render engine since render path type is NONE. Ignore this warning ifrendering has been turned off on purpose.
[Wrn] [ModelDatabase.cc:339] Getting models from[http://gazebosim.org/models/]. This may take a few seconds.


And then nothing happens (there being no X window is indeed "on purpose").

I've left this running for 30 minutes but there was no progress so I ctrl+c it.

Checking gazebosim.org/models/ myself I get the following page:

this could just be a default "indexing is not configured" error, or caused by me asking for index.html which doesn't exist of course. I noticed that models.gazebosim.org does work (but as I'm not an expert Gazebo user I don't know whether the two point to the same resources).

I guess the question is: is there some way to ascertain the status of gazebosim.org/models so we can gauge whether it makes sense to keep waiting for gzserver to complete the downloads?

I know this question has been asked before, before (#q6870, #q6347 and others), but seeing as there is a web server involved, those older questions (and their answers) might not be applicable any more, so here is a new one.

Starting gazebo --verbose results in an unresponse GUI with a black window and the same (similar) output on the console.

This is on a clean internet connection: no proxies, no caching proxies, no NAT, nothing.
