Cannot fully uninstall

[jfinkel]

Amplify did not work for me, so I uninstalled it using:

apt-get remove nginx-amplify-agent

But now when I try to update, I get this:

$ sudo apt update Hit:1 http://mirrors.linode.com/ubuntu hirsute InRelease Hit:2 http://mirrors.linode.com/ubuntu hirsute-updates InRelease Hit:3 http://mirrors.linode.com/ubuntu hirsute-backports InRelease Hit:4 http://mirrors.linode.com/ubuntu hirsute-security InRelease Ign:5 https://packages.amplify.nginx.com/ubuntu/dists focal InRelease Err:6 https://packages.amplify.nginx.com/ubuntu/dists focal Release 404 Not Found [IP: 52.24.43.197 443] Reading package lists... Done E: The repository 'https://packages.amplify.nginx.com/ubuntu/dists focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

How do I correct this? Thank you.

Answering my own question, I deleted a residual Amplify file in /etc/apt/sources.list.d/
