I'm at a loss to understand the problem, but this update declines to install on my system, with a logged complaint regarding a call to sock.bind(('', port)). Assuming there may be a port conflict, if the error detailed the conflicting port, the interfering service could be temporarily disabled, but that information doesn't exist. There is a line number referenced in a file in the /tmp directory, which might be useful except that the file appears to be removed when the installer exists.
I've attached the installer log, in hopes that someone might have some insight into the problem.
