• I am at the right place and my issue is directly related to ROS#. General technical questions I would post e.g. at ROS Answers or Stack Overflow. For library-specific questions I would look for help in the corresponding library forums.

What is the exact command to install gazebo 7.11 please? I could not open gazebo from roslaunch, and I did search online and could not find a line of code that was working. I could only install gazebo 7.14 (latest) or gazebo 7.0 (oldest). Thanks a lot.

• I searched the Wiki, open and closed issues for an answer. I tried my best to find the answer by myself without success. I believe that the discussion we will have in this issue, and the solutions we might find, will help me, and likely other community members who have a similar problem.

Please ask this question on ROS Answers.
It has nothing to do with ROS#.

Here's a hint @Xunzhaocunzi

I removed gazebo

sudo apt-get remove gazebo7*

Added Open Source Robotics to my sources

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

Added their key.

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

sudo apt-get update

Installed

sudo apt-get install gazebo7

Then I had 7.14.

I also have the version 7.14 , and it works well with Ubuntu 16.04 on the latest Oracle VM VirtualBox.
Please let us know if you encounter any problem while working with gazebo version 7.x.

So I am having an issue with it. For some reason I can't get the turtlebot to drive. It's receiving the /joy command, but it's just not moving. I've uninstalled and reinstalled gazebo7, ros-kinetic-turtlebot-gazebo a few times and it just doesn't move. I've tried driving with turtlebot keyboard teleop and still no movement. I've installed it on a native 16.04 Ubuntu installation and still it doesn't drive. Any help would be appreciated.

The main reason why we suggest users to have Gazebo with such particular version is because we once experienced an issue that Gazebo did not even work with Ubuntu on the VirtualBox. So if you can run Gazebo alone on your native Ubuntu, then there should not be any problem with the version of Gazebo.

I believe that the problem you are having is irrelevant to the topic of the issue here.

Yeah, I'll just keep digging at it. So weird, I followed the instructions on two fresh ubuntu 16 installations and it's giving the same problem. I'll keep digging I guess.

edit: @berkayalpcakal I logged issue in the correct place for this. So weird. I've been using ROS and turtlebot sim for years (on indigo) and never had so many problems with it.
