Problem installing packages on BeagleBone Black with ROS Hydro

edit

Hi everyone,

I'm having trouble installing packages in ROS Hydro on BeagleBone Black with Ubuntu ARM 12.04.

For example, when I tried to install vision_visp package, I did:

sudo apt-get install ros-hydro-vision-visp

But I get:

E: Unable to locate package ros-hydro-vision-visp

The same error seem to occur when I try installing other packages as well. There is no problem with the internet connection, since I can ping another computer, and also ssh from another computer into the Beaglebone. Could I have done something wrong during the Hydro or Ubuntu installation process?

Any help is much appreciated! Thank you.
