Comment 1 for bug 450147

Try this command:

    bzr upgrade --2a ftp://atat%40i360pro%<email address hidden>/testdeploy/

It appears that you've upgraded your local repository to the new format in 2.0.0, while your FTP server has a repository in either pack-0.92, 1.6 or 1.9 format. (bzr info -v can tell you exactly which if you're curious.)
