You are using this tutorial? http://wiki.ros.org/noetic/Installati...

I think you've skipped the 1.3 step:

sudo apt install curl # if you haven't already installed curl

curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

Redo the Noetic install from the tutorial.

Succes!

The 13th line above has this: Unpacking curl (7.68.0-1ubuntu2.6) ... Setting up curl (7.68.0-1ubuntu2.6)

Yes, that is the wiki page I followed. No keys are listed. Should they be listed?

Try again the tutorial. If necessary the key can be inserted there are tutorials for it. My assumption is that there was a server problem and some mistype command.

@Rodolfo8 if you run the command apt-key list, you will see this entry after you successfully install the signing key:

pub   rsa4096 2019-05-30 [SC] [expires: 2025-06-01]
      C1CF 6E31 E6BA DE88 68B1  72B4 F42E D6FB AB17 C654
uid           [ unknown] Open Robotics <info@osrfoundation.org>

You noticed the dash after the "apt-key add", right?

Yes, it worked fine today! Thank you
