I have a few Debian servers that are behind a firewall and they don’t have direct access to the internet. “Protected Servers”. I occasionally have to update their packages via a web proxy in the DMZ. I know there a countless ways to do this, but I wanted a one-liner that i can use without having to modify the apt-get application or my hosts default proxy settings.
Hope this helps someone else, cheers!
