Unable to install rosserial on Ubuntu 18.04, using ROS melodic

I am trying to interface ROS melodic and arduino. I tried installing rosserial from source but still coulnt see ros_lib in examples. I also could not find commands to install for melodic, that is why I went for source file. Thank you.

@colidar: you're issue would appear to be due to (for some reason) Ubuntu trying to use the IPv6 address to reach packages.ros.org, and failing. @ashutosh007 describes a very different problem.

Please post your problem as a new question.

I had the same problem. I followed this link: http://answers.ros.org/question/325039/apt-update-fails-cannot-install-pkgs-key-not-working/ Now it is working for me.
