Hello,

I followed the installation process for ROS Noetic on Ubuntu.

1) I set up ROS Noetic repo:

echo "deb http://packages.ros.org/ros/ubuntu focal main" | sudo tee /etc/apt/sources.list.d/ros-focal.list

2) Add official ROS keyring:

sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1...

3) Update ROS package index

sudo apt update

OUTPUT:

sudo apt-get update

Err:1 http://package.ros.org/ros/ubuntu focal InRelease Could not resolve 'package.ros.org' Hit:2 http://ports.ubuntu.com/ubuntu-ports groovy InRelease Hit:3 http://ports.ubuntu.com/ubuntu-ports groovy-updates InRelease Hit:4 http://ports.ubuntu.com/ubuntu-ports groovy-backports InRelease Hit:5 http://ports.ubuntu.com/ubuntu-ports groovy-security InRelease Reading package lists... Done W: Failed to fetch http://package.ros.org/ros/ubuntu/dists/focal/InRelease Could not resolve 'package.ros.org' W: Some index files failed to download. They have been ignored, or old ones used instead.

Which OS are you running this on? I guess this has been a connection issue. please confirm if this has been solved...

It looks like an internet connection problem, can you check if everything is right?

I have not had the chance to test out these suggestions since I haven't been able to get back to the lab. I will post an answer as soon as I am back. For now I am working from home using my own Raspberry Pi 3 B+, which am running into other issues with it.

Could not resolve 'package.ros.org'

Hmm the commands you pasted in the answer are ok, but this URL is wrong. It is supposed to be packages.ros.org with an S. Open /etc/apt/sources.list.d/ros-focal.list and double check that the URL there is correct.

typo: I think you meant packages.ros.org (not com)
