I'm using apt-cacher-ng to cache package downloads for my LAN. I'm also using the Ubuntu Beta fonts PPA which requires a password for access. I keep getting the error

bjorn@bjorn-laptop-natty:~$ sudo apt-get update

E: Some index files failed to download. They have been ignored, or old ones used instead.

It works properly if I disable using apt-cacher-ng. It seems weird that it says that it is trying to connect to 0.0.7.209; I'm pretty sure that's not the address of launchpad's PPAs. I don't always want to be changing settings just to check for updates, so how can I make apt-cacher-ng and a passworded PPA work together?

You can bypass apt-cacher-ng for certain hosts by using lines like the following in /etc/apt/apt.conf or the configuration file in /etc/apt/apt.conf.d/

Acquire::HTTP::Proxy::archive.example.org "DIRECT";
