Code review comment for lp:~mvo/update-manager/phased-updates

The code itself seems fine.

* OTHER_UNKOWN is a typo, should be OTHER_UNKNOWN

* Might you want to cleanUp from the amd64 setting?

* Running nosetests3, each of the new tests fails with (in addition to a new failure in the pep8 test):
Traceback (most recent call last):
