Comment 2 for bug 463093

This has been marked as a duplicate of bug https://bugs.launchpad.net/bugs/462828. It isn't strictly a duplicate, but that bug explains this one...

Bug 462828 refers to a potentially data loosing bug; the automatic updating system has been temporarily disabled at the server, giving a "Capabilities Mismatch" message at the client (user) end of the process. This will be reverted when bug 462828 has been fixed. Work is underway and a fix will apparently be published soon.

The Ubuntu One browser based interface can still be used to access. manage, upload and download files.
