cannot install ros packages by command line

edit

Hi,

I had the ROS groovy run on Gumstix Overo but I have trouble in installing ros packages with command line.

I want to install camera1394 so I type in sudo apt-get install ros-groovy-camera1394, however following error appears:

root@linaro-alip:~# sudo apt-get install ros-groovy-camera1394
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros-groovy-camera1394

Then I try to update the package list, and this is output of sudo apt-get update:

root@linaro-alip:~# sudo apt-get update

The output seems shorter than what I get from Ubuntu on my computer:
