The repository 'https://ppa.launchpadcontent.net/nginx/stable/ubuntu noble Release' does not have a Release file

Hi. After installing ppa:ondrej/php, I get the following error whenever trying to update apt update on Ubuntu 24.04:

The repository 'https://ppa.launchpadcontent.net/nginx/stable/ubuntu noble Release' does not have a Release file

The problematic file seems to be /etc/apt/sources.list.d/nginx-ubuntu-stable-noble.sources, which got added after install. If I temporarily disable the file, the update can proceed as normal. Does anyone have an explanation or solution for this?

Who added the /etc/apt/sources.list.d/nginx-ubuntu-stable-noble.sources file? It didn't magically appear.

And what are the contents of the file?

It was added or modified at the same time as installing ppa:ondrej/php.

And what are the contents of the file?

Nope, that's not true. This repository has nothing to do with ppa:ondrej/php. Check your scripts.

Sorry, it was caused by add-apt-repository ppa:nginx/stable recommended by various Nginx upgrade tutorials, yet the repository has expired.
