Comment 9 for bug 707392

No, that's the point: there isn't a PGP key, the package is not signed, and that's why Update Manager is complaining about untrusted packages. While this isn't ideal, (and I could at least do apt-get upgrade) I used to be able to upgrade it via Update Manager but now it seems I can't. Also, the error message in Update Manager doesn't give any indication of what you should do to move forward which isn't very friendly to newish users.
