ROS noetic installation failed at sudo apt-get update
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.
