--- Comment #22 from Adam Bolte abolte@systemsaviour.com --- To elaborate on what Berillions and super_man@post.com are saying:
Vanilla Wine 1.9.11, Uplay login doesn't work. If you have logged in before, you can click Settings (on the login pop-up) and click "always start in offline mode", and then you're in. So it doesn't seem possible to test cloud save without patches from staging right now.
It's easy to confirm this - just install Uplay into a clean prefix and try to log in. You'll get the message "A Ubisoft service is not available at the moment. You can try again later or switch to offline mode."
However Wine-Staging 1.9.10 patches (from bug 40271) do allow login to work without resorting to offline mode, and I can confirm that cloud-save does appear to work in the wine-staging environment.
All of the above described behavior was tested in a 32-bit Windows XP prefix with FarCry 3 installed without any DLL overrides.
A while back, Uplay used to open a pop-up that eventually stalled and indicated a cloud save failure, and asked (from memory) "Skip" or "Retry". That pop-up still exists, but then quickly disappears with Wine-Staging since saving appears to be working correctly with those patches. So I'm very eager to see patches for bug 40271 merged in, and for this bug to at least be marked as confirmed.
