ROS cannot find any package in new workspace

edit

I have two workspaces ws_A and ws_B with same packages. ws_A is the original and ws_B is a copy. I have gone through the catkin and overlaying tutorials with no avail. I have modified ROS_PACKAGE_PATH, done $ workspace_init, $ catkin_make on ws_B successfully, opened new terminals and done $ source ~/ws_B/devel/setup.bash. Regardless, a roscd package always sends me to the original ws_A folder. I've looked at other accepted answers and tried source /opt/ros/indigo/setup.bash first with no luck. It simply doesn't see ws_B. Using ROS Indigo and Ubuntu 14.04 Any help would be appreciated, in particular the exact steps required to see ws_B.
