For my work I rely on QNAP Qsync synchronized content. I can install on macOS, Mint, Windows but Fedora does not seem to offer an option. The .deb package cannot be installed apparently. Is there someone who got QSync working on Fedora? Download Center | QNAP
It appears QNAP is a paid-for product. You should get support from them for anything you purchase.
Which of the versions can I install on fedora: Essentials | Utilities | QNAP (UK)
Whichever works. Again it seems a paid-for product so they should provide the needed support.
