Cancelling update install renders system in corrupted stat

Hello,

Our QA team just found weird issue related to wyUpdate: cancellation of update install renders application into inconsistent state, and what's even worse, wyUpdate thinks that update succeeded, so it is impossible to restart update process.Taking into account that primary feature of wyUpdate is to keep application coherent, I think may be we're doing something wrong? Or can we have version of wyUpdate that has that nasty "Cancel" button disabled?

We can't reproduce this. All of our tests shows the correct behavior (roll-back on cancelled update).

We'll keep looking into it, but it would be helpful if you could make a test case for us.
