[ros-users] installation of ros-cturtle-base failed

Hi all,

I have a linux ubuntu 10.10 running on a virtual machine (Oracle VM
VirtualBOX).
I tried to install ros-cturtle-base but the installation failed:

$sudo apt-get install ros-cturtle-base

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
ros-cturtle-base : Depends: ros-cturtle-point-cloud-perception (=
0.3.2.2-r6361~lucid) but it is not going to be installed
E: Broken packages


Any idea?
Thanks.
