Jeroen, since you removed all your token server side, you need to remove your local token. To do so, please open seahorse (System -> Preferences -> Passwords and Encryption Keys) and remove the token named 'Ubuntu One'. Then, in a terminal, please do:
u1sdtool -q killall ubuntuone-syncdaemon killall ubuntuone-preferences killall ubuntu-sso-login And then, wait a few minutes and open ubuntuone-preferences again. Let me know how that goes! -- 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
