groovy openni 1.5.4 upgrade error

edit

Hi, after reading Tullys post on ros-users, I just upgraded to openni 1.5.4 on my Ubuntu 12.10 machine via upgrade manager. I got the following errors during the upgrade process:

"The upgrade will continue but the 'ps-engine' package may not be in a working state.Please consider submitting a bug report about it.
subprocess installed pre-removal script returned error exit status 127

Could not install 'nite-dev' Please consider submitting a bug report about it.
subprocess installed pre-removal script returned error exit status 127

Could not install the upgrades. The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a)."

So ps-engine is now a broken package, but I think that it is safe to remove it because now it is obsolete/deprecated, right? Besides, I runned openni_launch and image_view and the Kinect seems to be working. Regarding nite-dev, I don't know if it is necessary but the problem seems that there is no quantal version of the package available.

Cheers, Oier
