can't get apt-get to work with proxy

[emmostrom]

1. Tried setting http_proxy and ftp_proxy to:
http://username:password@proxy:port

Everything (apt-get and lynx) says it can't resolve host password@proxy
For some reason is thinks my password is part of the proxy URL

2. If I just set http_proxy and ftp_proxy to:
http://proxy:port

lynx works (asks for username and password) but apt-get has errors about proxy needing authorization.

Try editing the /etc/apt.conf like described here (in german)
http://www.x-fish.org/deb_apt-proxy.html

Or search with google for "apt-get" and "proxy"
