The main cloud services don't even work natively (GoogleDrive, OneDrive, iCloud) basically the only mainstream choice is Dropbox. I tried to use Google Drive in Mint, and it's a pain to get it to work, and usually it stops working after computer restarts.
Someone has a recommendation about how to handle these services?
Can't recommend Nextcloud enough. I also recommend checking out self-hosting! It's ridiculously easy to setup with the example docker-compose files they have in their git repo. If you have a NAS or a machine at home, you can basically create your own online storage that's completely private.
NextcloudPi is a fairly low-maintenance version of NC, the only way I'd recommend installing it besides as a docker image. Straight installing NC is a recipe for disaster, it's notoriously bad at updating that way.
Whatever you do, don't use the builtin web updater inside NC to update nextcloud itself. Their app updater is fine, but the actual Nextcloud web updater is utter dogshit and will break things.
