I tried to run sudo do-release-upgrade -d and I got this error

Traceback (most recent call last):
File "/usr/bin/do-release-upgrade", line 145, in <module>
fetcher.run_options += ["--mode=%s" % options.mode,
AttributeError: type object 'DistUpgradeFetcherCore' has no attribute 'run_options'

What do I need to do to fix this?
I was trying to see if I good get the ubuntu 13.04 dailybuild to install. I guess I should post a new thread for this, but can I upgrade to the daily build without having to install fresh from an ISO?
