Hello all,

I moved to Ubuntu 11.04 this week after ros was available for it. However there is an error when I want to install openni-kinect. 

The error message:


xiao@ubuntu:~$ sudo apt-get install ros-diamondback-openni-kinect 
[sudo] password for xiao: 
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
 ros-diamondback-openni-kinect : Depends: nite-dev but it is not going to be installed
E: Broken packages


And then I tried to find the dependency problem, 

xiao@ubuntu:~$ sudo apt-get install nite-dev

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 nite-dev : Depends: openni-dev (= 0.1.0~natty) but 1.1.0.41-5+natty1 is to be installed
E: Broken packages

It seems to be caused by openni-dev version,  I also tried to install it from source, however when I wanted to download the source, the following error came to me:
xiao@ubuntu:~$ hg clone https://kforge.ros.org/openni/drivers
warning: kforge.ros.org certificate with fingerprint 9b:29:7b:22:3a:35:9c:e6:6c:ca:fe:b7:64:eb:1e:cd:bf:01:0a:92 not verified (check hostfingerprints or web.cacerts config setting)
abort: HTTP Error 500: Internal Server Error


Any idea on how to solve this problem?

Cheers,
Junhao
