It's a somewhat similar issue AFAICT. The breakage happens right after
we copy in our local includes to the chroot. Specifically it seems like
config/chroot_local-includes/etc/apt/apt.conf.d/0000runtime-proxy is the
culprit as it sets:

    Acquire::http::Proxy "http://127.0.0.1:8118/";


As you can see in the end of the buildlog from my failed try to build
without any proxies, the above proxy is unsuccessfully used:

I had anticipated that this was the problem even before starting this
build, so in addition to squid-deb-proxy I had also turned off privoxy
that happens to listen on port 8118, the same port polipo listens on
inside Tails and that we want Tails' apt to use. That setting seems to
be overridden by the environment set in /etc/live/build.conf though, so
that's why it works for us using a caching proxy to build Tails.

I have to run now, so unless someone has fixed this until tomorrow I'll
have a look.

Cheers!
