I've looked into this a bit more and I think it's to do with the new
by-hash/ feature in the Ubuntu 16.04 repos:
$ ls /srv/packages/apt-cacher-ng-wily/uburep/dists/wily/main/
binary-amd64  binary-i386  i18n  source

$ ls /srv/packages/apt-cacher-ng-xenial/uburep/dists/xenial/main/
dep11  source

I'm guessing apt-cacher-ng doesn't support this? I can't find a way to
turn it off though.
