Unusable

Had high hopes but to be able to use this plugin to best potential you need to add a repository, according to the relevant guide which seems to date back 9 years.

Errors:-

E: The repository ‘http://ppa.launchpad.net/rtcamp/nginx/ubuntu 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.

So what’s the point?

I may be missing something (such as a guide that works? Am using your recommendation: https://easyengine.io/wordpress-nginx/tutorials/single-site/fastcgi-cache-with-purging/) so sort that out, let me know, and I’ll gladly update this review. Meantime, damn, that was a few hours wasted.
