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?
Nextcloud is everything other than minimization and stability. I bet if you take a quick look at their repositories you’ll find security-wise questionable stuff very fast and also tons of different pieces not a single thing.
