We're going to need more information from you (e.g., what version of Ubuntu are you using) in order to help

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]

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