I am seeing an issue with nextcloud not syncing a file within the folder that should automatically two-way sync. I have found that the file needs to be uploaded to nextcloud in order for syncing to happen, but once it is uploaded, it syncs normally when two way sync is enabled. I don’t think that has anything to do with you’re issues, but it’s food for thought.
Debian for servers, fedora/opensuse for desktop. I like Debian on server because it’s slow to change and every how-to will pretty much work with very little need for delving deeper. I used opensuse for a server for a little bit, but it was mostly an exercise in seeing how much I actually understood linux since there’s almost no directions for opensuse anywhere, so you really need to know how it works and translate instructions for other distros to it. I was using Tumbleweed and at one point there was an update that broke my networking that I couldn’t figure out, I wasn’t running anything really important on it, so instead of doing the instruction translation thing all over again for Leap (OK, I did actually do it, but I was already thinking of shutting it down and did a few months afterwards), I just took what I needed off of it, shut it down and moved the scraps onto my debian server.
I’ve used Debian for desktop as well and had zero complaints, it’s a little behind on updates because stability is more important. I’d actually put on par with a real enterprise distro, rather than the community testing ones like you get with Fedora and opensuse. Boring, does what it’s supposed to, misses a lot of vulnerabilities because they’ve already been fixed. All the new cool features that get added to everything shows up next release.
I liked Fedora a lot, it’s pretty really solid workstation (I use the KDE version, I’ve hated gnome with a passion since 3) but I’m not a fan of the direction IBM seems to be dragging redhat, so I’ve been transitioning to opensuse on desktop. Opensuse is pretty on par with Fedora, just a little different, but there are a few things that aren’t available of you need vendor software because they test on Debian and Fedora, release a .deb and .rpm and that’s the end of it. I keep a fedora VM around for one off packages that don’t work in opensuse or aren’t available. I’m taking some online courses, so the fedora VM is mostly used for the weird things my university requires that I can still use Linux for, and a windows VM for when things get real bad, which I haven’t actually used after the “learn to use Microsoft office” course.
I don’t do any gaming anymore or use any special purpose software for my normal use, so it doesn’t really matter to me which flavor I use. Except that I dislike gnome 3 because I have preferences that don’t fit the developers idea of hire a use should use their computer, and xfce because…I don’t really know, probably the right-click menu thing, I have no good reason.
