LGTM with a test tweak

File state/apiserver/client/client_test.go (right):

https://codereview.appspot.com/58490043/diff/1/state/apiserver/client/client_test.go#newcode1718
state/apiserver/client/client_test.go:1718: c.Assert(script,
gc.Not(jc.Contains), "apt-get")
Please add the opposite check to the test above this one to ensure

false
