I'm trying to install the hydro turtlebot simulator on Ubuntu 12.04 (32 bit) but the dependencies for openni seem a bit wacky. I've installed and uninstalled a few times now and nothing seems to work. It seems to boil down to ros-hydro-openni-launch refuses to install because it doesn't want to install ros-hydro-openni-camera even if ros-hydro-openni-camera is already installed.

The following packages have unmet dependencies:
 ros-hydro-turtlebot-bringup : Depends: ros-hydro-openni-launch but it is not going to be installed
 ros-hydro-openni-launch : Depends: ros-hydro-openni-camera but it is not going to be installed
ros-hydro-openni-camera is already the newest version.

If I have ros-hydro-openni-camera installed, and then do an "apt-get install ros-hydro-desktop-full", it removes ros-hydro-openni-camera, e.g.

Removing ros-hydro-openni-camera ...
Removing libopenni-dev ...
Removing libopenni-sensor-primesense-dev ...
Removing libopenni-sensor-primesense0 ...
Removing openni-utils ...
Removing libopenni0 ...
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
Processing triggers for man-db ...
Selecting previously unselected package openni-dev.

...and I'm back at square one.

I'm guessing there's a conflict between openni-dev and libopenni-dev Any suggestions as to how to get things installed properly?

Thanks, -Mark
