make posix_sitl_default gazebo problem

[wkyoun]

When I finished installing ROS Indigo, I noticed that it already came with Gazebo(version2.2.6).

If I directly install the 6.0 Gazebo, is it possible that the 6.0 version and 2.2.6 version will conflict with each other?

Actually, I have tried to install gazebo as described in

http://gazebosim.org/tutorials?tut=install_ubuntu&ver=6.0&cat=install

but, it says that : E: Unable to correct problems, you have held broken package

It looks like that I have Gazebo(version2.2.6) cause this problem

(gazebo which command indicate that I have Gazebo(version2.2.6)

How can I remove Gazebo(version2.2.6) came with ROS indigo?

I don't know how to remove Gazebo(version2.2.6) and install gazebo > 6.0 in order to

run make posix_sitl_default gazebo as described in http://dev.px4.io/simulation-gazebo.html

My situation is as follows:

wkyoun@wkyoun-XPS-13-9343:~$ sudo apt-get install gazebo6

Also, I tried to run Gazebo as described in

It says: "package 'gazebo>=6.0' not found". Is it installed and recent enough? Did you read the documentation? http://dev.px4.io/simulation-gazebo.html

If you're still having problems it would be better if you ask on the mailing list as this doesn't look like a bug but an incomplete installation.

@SimonWilks Please re-open this question,

I am new to github, how can I ask this on the mailing list?

Would you please let me know?

[SimonWilks]

Sure, you can either join the mailing list or gitter chat. You can find the infos here: https://pixhawk.org/community/start
