Found it! The token is called "UbuntuOne," but the one I deleted earlier was called "Ubuntu One" IIRC.
After connecting, the preferences UI showed my other Maverick system logged in multiple times. This is strange, since I had deleted those before and, as on this Maverick machine, I completely failed to log in. Once I get back to that machine (it'll take a number of weeks) I'll try the same procedure there. -- 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
