Attempting to get past proxy issues, why does setting apt.conf not work, but forcing a command through bash with export_http/https set does does?

Question

I'm trying to set the http/https_proxy values in apt.conf so that sudo apt-get will work for a proxy that I'm behind.

In /etc/apt/apt.conf:

Acquire::http_proxy::proxy "http://proxy.***.*****.com:8000/";
Acquire::https_proxy::proxy "http://proxy.***.*****.com:8000/";

When I run sudo apt-get update, it unfortunately times out saying it can't find the server.

However, when I execute apt-get update through this command:

sudo bash -c 'http_proxy="http://proxy.***.*****.com:8000" apt-get update'

sudo apt-get does work. I found that command from: How to run "sudo apt-get update" through proxy in commandline?

I also tried adding:

Defaults env_keep = "http_proxy htps_proxy" in '/etc/sudoers' or visudo.

I found this here:

How to run "sudo apt-get update" through proxy in commandline?

What am I doing wrong? I apologize for asking this as similar questions were already asked, but I can't solutions I've seen to work.

Answer 1

It's your syntax in the /etc/apt/apt.conf file.

Try this:

Acquire::http::Proxy "http://address.com:port";
