When I try to sync the repositories it ends with a few unfounded repositories. I used grep to filter them out here http://pastebin.com/9Lin3zCs. I have tried to replace them manually, that worked for some, but I was unable to not find a repository containing external/gpg.

I'm trying to build it for the Xperia Z1 with the standard sources, because the ones provided for minato seem to be even more out of date.
