Cannot install gazebo_ros_pkgs
I unistalled with :
sudo apt-get remove ros-kinetic-gazebo-ros
the gazebo_ros package and its relevant packages (in other words the whole gazebo_ros_pkgs was removed), but now when I type:
sudo apt-get install ros-kinetic-gazebo-ros
I get the following error:
E: Unable to locate package ros-kinetic-gazebo-ros
How is it possible ?
