APT does not support proxy auto-configuration, and never will, as this requires a JavaScript engine, which is not a good idea to run as root and depend on in a package with Priority: important.
But you should be able to write your own implementation by writing a script and set Acquire::http::ProxyAutoDetect to it. See squid-deb-proxy for an example script. ** Changed in: apt (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/651229 Title: software center/software updater/apt-get doesn't use proxy authentication info and gets no internet access Status in apt package in Ubuntu: Opinion Status in software-center package in Ubuntu: New Status in update-manager package in Ubuntu: Confirmed Bug description: System has internet access via a proxy server with authentication. All info is set in "System/Preferences/Network Proxy" and applied system wide. Update manager reports a "407" when trying to download. Firefox hasn't any problems using the system defaults. As we all know, synaptic has got its own proxy preferences. That works and this is the only way for updating the system.
