With due all my respects, If a powerful software is causing countless problems which are resulted by careless posting and maintenance, it will be a totally useless one and this is gazebo.

Could you please kindly have a look at your tutorials and release instruction on your website? Almost none of them works!

waiting for namespaces..... when executing

Unable to locate package gazeboXX.... when installing

Come on, what is the point to release your project and instructions when the users cannot get them?

Thank you for your attention.

-1. People here are happy to answer specific questions you have -- general complaints are really not constructive. If you have a question on how to do a particular thing: ask. If you have a feature request, make it. If you have a bug report, file it: https://bitbucket.org/osrf/gazebo/issues?status=new&status=open

Sorry to hear that you had a bad experience. Hopefully we'll be able to assist you.

I'll need a bit more information though. Could you update your post with answers to these questions?

  1. What version of Gazebo are you using?

  2. What operating system are you using (such as Ubuntu Trusty, or OSX)?

  3. What tutorial(s) did you try to follow?

  4. What command did you execute that resulted in "waiting for namespaces....."?

  5. What command did you execute that resulted in "Unable to locate package gazeboXX...."?

Every release we run through our tutorials to make sure they work. Sounds like we missed something, and we'll try to correct this situation as fast as possible.

Thanks for letting us know about your problem.

* Update *

So far you have said that you followed the tutorial exactly, and still can't install gazebo7. If this is the case, then something strange is going on. Can you please post the output to the following commands:

sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'

.

 wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -

. just post the last couple lines of the next one

sudo apt-get update

.

sudo apt-get install gazebo7

The author of this question had Ubuntu 12.04, not 14.04 as originally reported. Therefore they could not install gazebo7 as indicated here (http://gazebosim.org/#status).

Hi,

Thank you for your reply.

Ubuntu 14.04, an indigo on it with the installed gazebo2 which causes "waiting for namespaces..." (like this http://answers.ros.org/question/19940...)

To avoid that "waiting for namespaces", I turn to new versions of gazebo and tried to install it via http://gazebosim.org/tutorials?tut=in... got the "unable to locate gazebo7"

These errors are really annoying to me because I am working on a coding and algorithm work and didn't expect such much time (weeks) spent in making existing simulation package work. The main complaint from that I think the project should have the property of downward compatibility. But I cannot see it in Gazebo (and ROS, another rough story..).

Thank you again for your time.

It sounds like you are using gazebo with ROS. I suggest you look at these tutorials: http://gazebosim.org/tutorials?cat=connect_ros Could you also completely answer all of my previous questions? I still don't know how to help you because you have not included any technical information specific to your problem (console output for example). If you'd like to express frustrations, please email me directly and save this forum for useful discussions.

Did you run the first two steps of getting packages.osrfoundation.org and updating your keys?

nkoenig gravatar imagenkoenig ( 2016-04-01 17:25:06 -0600 )edit
