I am still new to ROS and gazebo and I am also not a pro on linux so pls help. I was following this https://www.generationrobots.com/blog/en/robotic-simulation-scenarios-with-gazebo-and-ros/ tutrial step by step on how to setup a simple robot and connect it with ROS to control the bot. After adding the controllers I got the error:

ERROR: cannot launch node of type [controller_manager/spawner]: controller_manager
ROS path [0]=/opt/ros/kinetic/share/ros
ROS path [1]=/home/thifer/catkin_ws/src
ROS path [2]=/opt/ros/kinetic/share

Apparently the problem was that ros-control was not installed. I tried to sudo apt install ros-kinetic-controller-manager ros-kinetic-ros-control ros-kinetic-ros-controllers but none of these packages can be located. It looks like apt can't locate any ros package that is not installed yet. I tried installing packages form source but I get stuck in an endless loop of installing dependencies of dependencies of dependencies all from source. I figured out that the problem should be located in the source.list and source.list.d files but they look exactly like they are supposed to look according to the web.

source.list:

# deb http://ftp.nl.debian.org/debian jessie main

deb http://ftp.nl.debian.org/debian jessie main non-free contrib
deb-src http://ftp.nl.debian.org/debian jessie main non-free contrib

ros-latest.list: (commented out because duplicate warnings)

# deb http://packages.ros.org/ros/ubuntu jessie main

ros_packages.list:

# This file is managed by Puppet. DO NOT EDIT.

deb http://packages.ros.org/ros/ubuntu jessie main

I am using ros kinetic on ubuntu jessie amd64
