kobuki installation error (Unable to locate package)
I am currently trying to install the kobuki package using:-
sudo apt-get install ros-kinetic-kobuki ros-kinetic-kobuki-core ros-kinetic-kobuki-gazebo
which is as mentioned in the tutorials in the following websites, http://wiki.ros.org/kobuki/Tutorials/... and http://wiki.ros.org/rrt_exploration/T... . However in each case I get the error
E: Unable to locate package ros-kinetic-kobuki
E: Unable to locate package ros-kinetic-kobuki-core
E: Unable to locate package ros-kinetic-kobuki-gazebo
This is also true when I try to do the same using ROS melodic. Has this package been stopped or removed? or am I required to install something before installing these packages?
