install kobuki on melodic: error

edit

Hello, I tried to run the below code to "compile kobuki from its source codes" because kobuki for melodic seems not being released. (referring to a Japanese textbook I'm reading to learn ROS) Thank you very much in Advance

OS: Ubuntu 18.04 on Virtualbox ROS: melodic

CODE

$ curl -sLf https://raw.githubusercontent.com/gaunthan/Turtlebot2-On-Melodic/master/install_all.sh | bash
$ catkin_make

What I got(copy & paste from the terminal):

taka@taka-VirtualBox:~/catkin_ws_2$ curl -sLf https://raw.githubusercontent.com/gaunthan/Turtlebot2-On-Melodic/master/install_all.sh | bash
