Ubuntu trying to use the IPv6 address to reach packages.ros.org while installing rosserial for melodic

I'm using ROS melodic with ubuntu 18.04 running on a Thinkpad. I want to install rosserial for my arduino uno with this tutorial: http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup

When i'm running: sudo apt-get install ros-melodic-rosserial-arduino

i get these errors:
