Gazebo Not Responding on launch

I can verify similar symptoms from my setup. Working backwards in the default branch, the issues seems to arise with this commit/merge (rev=186): https://osrf-migration.github.io/vrx-gh-pages/#!/osrf/vmrc/commits/3e6600a0c6ba6731087a34fa4fbbcad8f1d5f170

For me the default branch was operational prior to the commit, but not after.

@kev-the-dev , @caguero - can you see if the most recent default branch works for you?

Cannot replicate after doing a clean build. Perhaps it's some old stuff running.

A few general steps to rule out other issues:
Update packages

sudo apt update
sudo apt upgrade

Do a complete rebuild:

cd <your workspace>
rm -R devel/ build/
catkin_make

Make sure no other gazebo instances are running

ps aux | grep gz

For my setup, the issue seems to be with the sandisland/model.sdf file.
If I do this...

hg revert -r178 ~/tmp_ws/src/vmrc/robotx_gazebo/models/sandisland/model.sdf

then things are back to a working state.

Looking at the changes, not sure why adding simplified collision geometry would affect. Also, probably worth debugging why we are getting different results with different setups.

I've verified - to the best of my knowledge - that having the system up to date, no other gazebo processes and clean workspace and fresh clone of the head of the default branch causes gazebo to hang.

It's a long shot, but could one of you try running the sdf-warn branch in PR #23? Maybe the SDF version makes the box collisions invalid.

Will try it a bit later today.

Tried the sdf-warn branch without any luck - Gazebo still hangs.

Need to add instructions in setup tutorial to make sure and use the gazebo (not ros) Ubuntu packages.

E.g., http://gazebosim.org/tutorials?tut=install_ubuntu

This bug shows up when using Gazebo 7.0.0 from the ros package repo, but if you add the gazebo package repo, and update, you should have at least version 7.13.1. With this version the bug is fixed!

Will close issue once we get docs up.

Added to install instructions

• changed state from "new" to "resolved"

Issue was making sure to use the gazebo package repository (instead of the ros repos) so that the gazebo7 install is upgraded from 7.0.0 to 7.13.1
