I'm still having the problem. I also tried removing all connected devices, though from the desktop client. (This is also Maverick BTW). I also rebooted a few times since then. But I still can't connect; my connection status is permanently "Disconnected," my usage meter says 0.0 KB (0.0%), the Devices tab shows "<LOCAL MACHINE>" as the only connected device, the Connect button is grayed out, and the Restart button does not have any apparent effect.
I tried running "u1sdtool -q ; u1sdtool -c" but all it does is print "ubuntuone-syncdaemon stopped." It no longer opens a login dialog (as it did just a few days ago). A "ps -ef | grep ubuntu" shows two processes: * /ubuntu-sso-login started hours ago, around last boot. * ubuntuone-preferences does not go away when I close its window. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/696361 Title: Ubuntu sso fails with 'An HTTP non-2xx response code was received' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
