I'm glad this method is shining a light on your problem. I'm afraid that I'm not very experienced in running the many apt* commands available, but others may help. > (BTW, this package is taken from jessie but there is an existing > backport package.

One *might* try the brute force approach of just telling it to reinstall everything on your system, but specifying -t jessie-backports as the target, and -s of course to prevent anything happening while you checked. But I don't know the answer. Cheers, David.
