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.

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.

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.

I bought Moon Reader Pro a million years ago cheep on sale, and it has been great. Still love it, but I like to check out open source readers every once in a while.

Lately I have been using Librera FD. This open source version on f-droid unfortunately has the network features (sync/opds) disabled. The play store version has those enabled. The interface is a bit unusual, but it’s a powerful and flexible reader.
