Glenn, if you don't have Internet connectivity at the system level, it
looks like apt can be configured to use a proxy as well.

Create /etc/apt/88proxy containing the following:

Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/";
Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";

The <details> can be taken from the wpad.dat file.
