And if I’m using synaptic, how do I set those options? The only place I’ve found is for setting an internal option… Oh, wait - how about /etc/apt/apt.conf? I don’t seem to have one, can I simply create it and put something like: APT { Get { Acquire::http::AllowRedirect “false”; }; }; And be good?

Use '-o Acquire::http::AllowRedirect=false' option for apt tools to disable the redirect that's vulnerable in order to install the updates.
