Hi everyone,

I've been having an issue with the openni drivers when I try to use RBGDSLAM on Ubuntu 12.04. I've installed the RGBDSLAMV2 package on my machine, but in order to run it I need to install `opennilaunch`. When I do this, I get the following error:

ros-hydro-openni-launch : Depends: ros-hydro-openni-camera but it is not going to be installed Unable to correct problems, you have held broken packages.

When I manually install this dependency, I found that openni-dev was conflicting with libopenni-dev. I then uninstalled the former completely and installed openni-camera with no problem. However, when I then go back to install openni_launch I get the same initial error:

ros-hydro-openni-launch : Depends: ros-hydro-openni-camera but it is not going to be installed Unable to correct problems, you have held broken packages.

I did some sleuthing and it seems to be related to the PCL repo and 12.04? I've had this error every time I try to install ROS and RBGDSLAM_V2. I've also tried reinstalling Ubuntu and PCL multiple times to no avail.

I've seen this error pop up on some other forums, but I cannot find a working solution to this problem. Can anyone here help me with this or give some pointers?

Thanks!
