cannot install package with apt [closed]

edit

Hi, I'm trying to setup ros on a Pandaboard, running Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-1412-omap4 armv7l). After running apt-get update I cannot install anything about ros, because apt cannont find any package starting with ros:

vision@panda-vis-01:/etc/apt/sources.list.d$ sudo apt-get install ros-fuerte-ros-comm
Reading package lists... Done

E: Unable to locate package ros-fuerte-ros-comm

Y've set the repository to universe and multiuniverse, but still the same problem. Please help me.
