Please bear with me, I've searched as best I can with no apparent solutions.
I'm behind my companies firewall, we have a couple of proxy servers that we can use to get out onto the big wide internet. My company's IT group has kindly mirrored the main Debian repos inside the WAN.
I would like to use a couple of repos outside the WAN (i.e. the Internet). Is it possible to tell apt-get to use a proxy for these, and not for the others?
With both enabled and a proxy defined in apt.conf, it barfs on the stuff inside the firewall, and without a proxy defined it barfs on the sources outside the firewall.
There is some mention in the man page for apt.conf, but putting a proxy statement in the source.list file doesn't work (unless I've got the syntax wrong).
