I am new to ROS and as part of the tutorial, I am trying to install the hokuyo laser driver and have tried all the solutions posted so far but I keep getting the same error message
sudo apt-get install ros-fuerte-laser-drivers
E: unable to locate package ros-fuerte-laser-drivers
and
sudo apt-get install ros-hydro-urg-node
E: unable to locate package ros-hydro-urg-node
I am using Ubuntu 14.04 running on VirtualBox. I have ROS indigo igloo. Please help
