How do I add a repository from behind a proxy?

I would like to send an add-apt-repository command via the gnome-terminal on my Ubuntu 11.10 laptop that is connected through a proxy (with username/password). Following this answer, I edited my apt.conf file:
how to install packages with apt-get on a system connected via proxy?

/etc/apt/apt.conf

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

I can now run apt-get install package-name with no problem, but when I try add-apt-repository, it won't work. Any suggestions?

sudo add-apt-repository ppa:bumblebee/stable

You can try as suggested here, as someone has already solved this problem:

Solution 2

This is a known bug.

According to one of the subscribers you can go around this by using these steps:

sudo visudo

then add the following lines

Defaults env_keep="http_proxy"
Defaults env_keep="https_proxy"

then:

sudo bash
export https_proxy=http://[username:password@]www.proxy.com:8000/
add-apt-repository ppa:<whatever>
