Hi all,

Sorry if this has been asked earlier, but as far as I have searched I
cannot find a solution to my problem. I am running ROS Groovy on Ubuntu
12.04.

I would like to install ros-groovy-visp (please note there is also
ros-groovy-vision-visp but this does not install everything that I need,
e.g. it does not install visp_auto_tracker and manually trying to install
it didn't work). However, when I try to install ros-groovy-visp I get the
following error:

(sudarshan)$ sudo apt-get install ros-groovy-visp

So, I try to install libfreenect0.0, which ends up removing libfreenect
libfreenect-demos and libfreenect-dev:



(sudarshan)$ sudo apt-get install libfreenect0.0

The following NEW packages will be installed:

  libfreenect0.0

But on trying to install ros-grooy-visp now, it fails citing unmet
dependency since libfreenect-dev is not installed:

(sudarshan)$ sudo apt-get install libfreenect0.0

Obviously, installing libfreenect-dev removes libfreenect0.0. I have been
struggling to solve this conflict for a while, if anyone has any suggestion
to fix this, I would be very grateful. Please let me know if you need any
more information.

Thanks.
