Well i have faced the same problem, I did follow all the instructions in the videos, however the installation was for indigo, changing just the word "kinetic" doesn't work so i found a solution, use "apt-cache search ros-kinetic" in terminal. This will show a long list of packages supported by ros kinetic, now look for all turtlebot related packages. To install use the usual "sudo apt-get install pkg_name". You have to install all the packages one by one manually there is no single code line that would install all the packages relate to turtlebot, however you can install all at-once by just adding all the package name next to each other like this
sudo apt-get install pkg_name1 pkg_name2 pkg_name3...............
press "y" to install and then to check installation do this
roslaunch turtlebot_gazebo turtlebot_world.launch
You can also install other packages like this when you are unable to find a source to install.
Hope this helps.
can anyone help me ..? :(
