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?
Yes, it’s often possible to get unsupported services working, but it’s rarely simple and it’s prone to breakage over time with changes to the system as well as to the service. I do not recommend it to anyone seeking a simple solution and I will not do it for someone I need to support.
