How to make ROS Indigo work with Gazebo 4? [closed]

edit

I ran into the same issue attempting to install ros-indigo-gazebo-ros: I'd previously been working through the Gazebo tutorials and had installed Gazebo 4, per the instructions. Then came to realize that Indigo needs Gazebo 2, as explained here. As a previous post mentioned, you need to remove Gazebo 4 and install Gazebo 2:

sudo apt-get remove gazebo4
sudo apt-get install libsdformat1
sudo apt-get install gazebo2

Not sure if the second step was actually necessary; I was just chasing the dependency warnings. Hope that helps.

This is what I see in my Ubuntu 14.04:

~$ dpkg -s ros-indigo-gazebo
ros-indigo-gazebo4-msgs
ros-indigo-gazebo4-plugins
ros-indigo-gazebo4-prerelease-msgs
ros-indigo-gazebo4-prerelease-plugins
ros-indigo-gazebo4-prerelease-ros
ros-indigo-gazebo4-prerelease-ros-control
ros-indigo-gazebo4-prerelease-ros-pkgs
ros-indigo-gazebo4-ros
ros-indigo-gazebo4-ros-control
ros-indigo-gazebo4-ros-pkgs
ros-indigo-gazebo-msgs
ros-indigo-gazebo-plugins
ros-indigo-gazebo-ros
ros-indigo-gazebo-ros-control
ros-indigo-gazebo-ros-pkgs

So it seems there are some indigo-gazebo4 packages. Did you try that (like apt-get remove ros-indigo-gazebo-* && apt-get install ros-indigo-gazebo4-*)?

I don't wanna try and hassle my own system, though, so sorry for I haven't tried that before posting the answer.

It should be possible , follow below link:

Maybe you should run ROS indigo with gazebo2.

They say ROS indigo works best with gazebo2, which is difficult to install because of dependency. It requires libsdformat-dev (and therefore libsdformat1) that has version >=1.4.11-1 but <2.0.0 which is almost unable to satisfy. However I found those versions of those dependencies that perfectly matches and allow you to install gazebo2.

However remember to remove the existing updated versions of those libraries before installing packages above:

sudo apt-get remove libsdformat-dev
sudo apt-get remove libsdformat1

Otherwise Ubuntu Software Center would tell you about dependency problems and won't allow you to install.

After installing the 2 libs above you can now install gazebo2 which is supposed to work best with ROS indigo.

sudo apt-get install gazebo2
sudo apt-get install ros-indigo-desktop-full

As in the link @Mos provided, Gazebo team provides a way to have newer version (Gazebo6 here) side-by-side with Gazebo2.x, which was announced here.

UPDATE; Looks like no side-by-side installation is possible yet with the method in the link above.

UPDATE2: Using Gazebo of the higher version than 2.x on Indigo is an FAQ. See Migration Note for ROS Indigo.

I had a similar problem, but just installing Gazebo 2 per the directions.

I'd had Gazebo running on Ubuntu 12.04 LTS. I wanted to upgrade Ubuntu to 14.04. The Ubuntu upgrade failed, due to a package conflict in ROS/Gazebo. (Ref: https://bugs.launchpad.net/ubuntu/+so... ). So I had to uninstall ROS/Gazebo to upgrade Ubuntu. The Ubuntu upgrade went fine.

Then I tried to re-install ROS/Gazebo, following the directions at "http://wiki.ros.org/indigo/Installation/Ubuntu".

This produced errors: ... (Reading database ... 95% (Reading database ... 100% (Reading database ... 311085 files and directories currently installed.)

dpkg: error processing package gazebo2 (--configure): dependency problems - leaving unconfigured

This put the package manager into an endless loop of trying to repair, failing to repair, and asking to try to repair again. I had to reboot and do "apt-get remove gazebo2" to get the package system into a valid state again.

Now what?

Do you need Gazebo 4 for your project? What project, and to what extent do yo need to use the features that are exclusively in Gazebo 4?

I actually would need to install Gazebo 4 for running the DRCsim demo : http://gazebosim.org/tutorials?tut=dr... but when I follow the tutorial, it requires to remove ros-indigo-desktop-full to install the package drcsim. Anyone manage to get that working ? (I'm using Ubuntu 14.04 and ROS Indigo)
