Comment 13 for bug 965017

I'm not going to update duplicity to 0.6.19 in 12.04. I could apply a small patch, but it would have to be rather targetted, and I'm not sure how easy the backport is.

Ken or Ed, do you know how easy it is to backport the .ssh/known_hosts fix?

In the meantime, you can workaround it like in comment #2.
