Unable to install wine due KEY

[scipio1200]

Hello there,

I'm relatively new to wine and I can't get it to recognize the key provided by the installation process via command.

Here is my terminal output:

It says no PUB KEY available even though I got the key from the previous stage, so I don't know what to do know. Be patient pls, as I said before, I'm kinda new to this.

That's not the WineHQ repository. Problems with that PPA should not prevent your installing packages from dl.winehq.org, and should be reported to the maintainer of that PPA, not here.
