How can I install Hydro and Indigo alongside on Ubuntu 14.04.
I installed indigo resourcefully.PR2 is supported only for Hydro.I tried installing hydro by following official doc ( http://wiki.ros.org/hydro/Installatio... )
I get following error
$ sudo apt-get install ros-hydro-desktop-full

E: Unable to locate package ros-hydro-desktop-full
I have also run apt-get update cmd before running above command
