Comment 1 for bug 1282759

Same symptoms on a fully up-to-date Ubuntu 13.10 64-bit install. Logs show same error messages. Toast notifications keep appearing suggesting that files are being uploaded to Ubuntu One, but nothing is ever uploaded. u1sdtool --quit and u1sdtool --restart work as expected, but the daemon never progresses past the authentication stage.

Incidentally, an Ubuntu One client running on an up-to-date OS X Mavericks install is also exhibiting similar symptoms and refusing to connect, again suggesting a server-side error. Could someone at Canonical possibly update the Ubuntu One Status page, 'cos at the moment it's full of 'status messages' dating from between 2011 and 2013 but absolutely nothing on the file-sync side of things.
