Hi,
Are you referring to this?
Code:
If you're trying to use apt-get from command line, you
can add this to your "/etc/apt/apt.conf"
Acquire::http::Proxy
"http://username:passwd@proxy.domain.com:8080";
Got that one from the Ubuntu lists archive. That's the one you could set for using apt, I'm sure you could do it the same for other apps, but don't know where to put it.
Kind regards,
Eric
