According to the gazebosim wiki, version 1.9.x of gazebo should be installed when ros hydro is installed but for reasons unknown I'm getting gazebo-current (i.e. version 2.x.y) installed. Any idea why?

I'm entering:

sudo apt-get install ros-hydro-desktop-full

and the output is:

The following NEW packages will be installed:
gazebo-current ...

I've also had gazebo-current install earlier but have since removed it.

It boils down to the fact that there are two debian repositories (ROS and OSRF) offering different versions of gazebo_ros_pkgs and gazebo / gazebo-current.

ROS Repository:

provides gazebo 1.9.x and gazebo_ros_pkgs 2.3.x for hydro as ros-hydro-gazebo-ros-pkgs.

OSRF Repository (this was created for DRCSim and for testing gazebo_ros_pkgs against newer versions of gazebo):

provides gazebo 1.9 and gazebo-current 2.1
provides gazebo_ros_pkgs 2.4.x for hydro as ros-hydro-gazebo-ros-pkgs that depends on gazebo-current 2.1.

To make sure you do not end up installing the version of ros-hydro-gazebo-ros-pkgs 2.4.x that uses gazebo-current, remove /etc/apt/sources.list.d/gazebo-latest.list or /etc/apt/sources.list.d/osrf*.list or comment out its content:

# deb http://packages.osrfoundation.org/gazebo/ubuntu [quantal/precise/...] main

Then remove gazebo-ros-pkgs and gazebo, update and reinstall:

sudo apt-get remove gazebo-current ros-hydro-gazebo-ros-pkgs
sudo apt-get update
sudo apt-get install ros-hydro-[...]

Note that we are in the process of renaming ros-hydro-gazebo-pkgs 2.4.x in OSRF repo to ros-hydro-gazebo-pkgs-current to avoid confusions.

My solution was to first install gazebo (version 1.9.x) via sudo apt-get install gazebo, then do a sudo aptitude install ros-hydro-desktop-full and one of the installation alternatives was to keep the current gazebo simulator version rather than installing gazebo-current. So in that sense, it's solved :-)

Just for curiosity though, I'm still unsure why the package list for apt-get install would be affected by the files on my computer. Shouldn't it be pulling that list from a server? Why would it be different depending on which computer I'm using? If anyone cares to explain or point me to an explanation, I'd be very grateful.

" one of the installation alternatives was to keep the current gazebo simulator version rather than installing gazebo-current." How did you initialize the installation alternative?

After the "sudo aptitude install ... " command, the terminal came back with a list of changes to packages, including installing some, deleting some and leaving some alone and asked "Accept this solution?". I just entered "no" until it offered to keep the already installed gazebo package while installing the rest of ros.

Install: 1) ros-hydro-gazebo-plugins [2.3.3-0precise ...] 2) ros-hydro-gazebo-ros [2.3.3-0precise...] Keep at their current version: 1) gazebo-current [Not Installed] 2) .... Is this the version that I am suppose to look for?

That looks about right, but I'm not 100% sure. Can you test it out?

I have tried and it works. Many thanks for help.
