that does not have a 'content_id' field in it.

sstream-mirror is just part of 'simplestreams' package in saucy.

which means this breaks for me

$ sstream-mirror -vv https://swift.canonistack.canonical.com/v1/AUTH_526ad877f3e3464589dc1145dfeaac60/juju-dist/tools/streams/v1/index.json out.d

hi Ian.

I think bug is fixable while you work on sync-tools to provide CPC files.
