Troubles installing ROS Kinetic on Linux Mint Sarah 18

edit

I am currently trying to install ROS Kinetic on my Linux Mint 18 running laptop. As far as I am aware of, Sarah 18 is based on Linux kernel 4.4 and an Ubuntu 16.04 package base. Following the wiki installation manual, I am running into the following errors (when calling apt-get update):

E: Some index files failed to download. They have been ignored, or old ones used instead.

Is this problem related to the fact that I am not using Ubuntu? Are there any methods of installing ROS on Linux Mint Sarah 18?
