self-update broke rpi-update

[jemertz]

There appears to have been a server error when rpi-update attempted to self-update which broke it.
pi@raspberrypi ~ $ sudo rpi-update

pi@raspberrypi ~ $ cat /usr/bin/rpi-update

503 Service Unavailable

No server is available to handle this request.

It appears to me that the server returned a 503 error and for whatever reason rpi-update used this error response to overwrite itself. I'm quite surprised that there wasn't a sanity check to prevent this, and strongly recommend adding one.

I believe the source has moved for the update. I recently installed the rpi-update and was greeted with not found and syntax errors executing "sudo rpi-update". I ran "cat /usr/bin/rpi-update" prior to a successful installation, and it details a 301 error- moved permanently. This is the new source:

https:// raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update

My suggestion is to execute the following:
$ sudo wget https://raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update
$ sudo rpi-update

That ought to replace the old rpi-update in your bin with the one that points to the right one.

Hope it helps!
