As long as the backdoor is licenced GPL what’s the problem?

I haven’t tried it but I’ve been thinking about it… Since NextCloud supports s3 storage it would seem its photo apps, such as Memories should work that way?

Thanks for the link. Yeah, my server is old. COPS is old, but still works great for me. .

Calibre has built in server, but while running server (last I checked) it locks the db so you can’t do much with the Gui, can’t add books etc. Also I’m already running a a web server with php so it’s more efficient just to slap the COPS web app there rather than run yet another server.

Similarly I use COPS (php calibre front-end)… But with no users or auth. If you can guess the URL you are in! Exciting.

Works well with nextcloud also.

Aves is really good. Used Simple Gallery Pro for years and it was great. But switching to Aves is painless for me.

AppStream makes machine-readable software metadata easily accessible. It is a foundational block for modern Linux software centers, offering a seamless way to retrieve information about available software, no matter the repository it is contained in. It can provide data about available applications as well as available firmware, drivers, fonts and other components. This project it part of freedesktop.org.

It works in the current Firefox for Android beta version.

There are a few attempts things like this. Here is one… https://fedi.directory

Maybe check out Pop! OS

But, yes, nearly all linux software will run on any distro. And even a fair amount of windows software will run on any of them with WINE (or VirtualBox if desperate). Occasionally commercial software will get packaged in an “installer” format a particular distro doesn’t know how to install. A fairly rare situation, for which there are almost always work-arounds. You can cross that bridge if you ever encounter it.

What features are locked? I’ve only ever used the f-droid version, and haven’t noticed anything blocked. But I don’t use it much (unfortunately).
