PPA Not Working Ubuntu 22.04

When I add the PPA, I get a weird output & it fails to verify the security.

Try

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A2166B8DE8BDC3367D1901C11EE2FF37CA8DA16B

as explained in the README.

How did you add the repo?

[InklingGirl]

How did you add the repo?

sudo add-apt-repository ppa:apt-fast/stable
sudo apt update

As per standard for PPAs.

As per standard for PPAs.

That should have added the key. Anyhow, is it solved now?

[InklingGirl]

No, the same GPG error occurs.

[gothicVI]

Even though you manually added the key?

@InklingGirl Any updates on this?

[gothicVI]

I guess this can be closed. Sounds like an error on the user system after all.

@InklingGirl Any updates on this?

I spun up a VM & there's no problem adding the PPA w/ add-apt-repository, so it's just that something is wrong w/ my host system.
