+Our proxy setup at work prevents APT from downloading packages
+ APT needs to be told how to access the proxy. Talk to your local sysadmin
+ and ask for the proxy's address (maybe a username and password too), as well
+ as the ports for HTTP and FTP proxies. With this information add the following
+ lines in the file, /etc/apt/apt.conf.d/80proxy. This will ensure that after an
+ upgrade changes won't be lost::
+
+ Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
+ Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/";
+ Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";
