Hi Everyone, I'm using ROS Hydro on Ubuntu 12.04 and trying to build some applications with roscontrol and roscontrollers, however when I type the command in the terminal according to the ros wiki page:

sudo apt-get install ros-hydro-ros-control ros-hydro-ros-controllers

The terminal showed the following error:

E: Unable to locate package ros-hydro-ros-control
E: Unable to locate package ros-hydro-ros-controllers

Do the hydro branch debian packages stop being maintained ? However I can successfully build them from source
