Earlier quoted context omitted.
Its too bad its still flakey at updating apps. I've been using it for a few apps for many years, and I'd say easily half of app updates simply fail for non-obvious reasons. Its been this way across multiple devices and countless versions of Android, so I'm left to believe the problem is with F-droid itself.
I also heavily heavily hate the idea that they sign everything, the app stores must not be trusted. They should only be signing over packages already reproducibly compiled.
Why? Isn't that how signatures of any Linux distro work too? The packager signs the package not the developer.
