I have recently installed Ubuntu version 16.04 and trying to install ROS kinetic on my laptop. However, I got stuck at this point where after running
sudo apt-get update.
This is the result:
Err:1 http://packages.ros.org.ros/ubuntu xenial InRelease Could not resolve 'packages.ros.org.ros' Hit:2 http://security.ubuntu.com/ubuntu xenial-security InRelease Hit:3 http://id.archive.ubuntu.com/ubuntu xenial InRelease Hit:4 http://id.archive.ubuntu.com/ubuntu xenial-updates InRelease Hit:5 http://id.archive.ubuntu.com/ubuntu xenial-backports InRelease Reading package lists... Done W: Failed to fetch http://packages.ros.org.ros/ubuntu/dists/xenial/InRelease Could not resolve 'packages.ros.org.ros' W: Some index files failed to download. They have been ignored, or old ones used instead.
I have searched for a solution online for quite awhile now, but still cannot seem to solve the issue.
