Windows 10 WSL Ubuntu 18.04 proxy configuration for apt.

Using Windows Subsystem for Linux (WSL) can be a great tool for dev's, op's, and admin's alike. The downside often these roles are after larger organization that gave Firewalls and tight proxy security.

I found myself in this exact situation. The corp. proxy uses a *.pac file script. Nothing in the Debian world does. Ugg. Here is how I got Debian apt to work behind a proxy.

Original Solution Source from theΒ Linux Questions Forums.

wget http://some.domain.tld/some-proxy.pac

...or you can probably just open it with a browser.

Look for the proxy address that is used if all other options fail. Typically towards the bottom / in a function call of its own.

    function FindProxyForURL(url, host) { return "PROXY; DIRECT"; }

Take note of the URL:PORT address.

Finally, put this in your /etc/apt/apt.conf file:

    Acquire::http::Proxy "";

Log out and back in. At this point apt-get update -y and related apt commands should work as expected.

Use GNU/Linux

Sadly in the business world 95%+ of computing machines will run Windows; VMs are a valid option but with bare bones hardware it would be un-usable. WSL is a nice middle ground.

It's proprietary, non-free and just ... objectivly speaking bad (unlike macOS, for example). Also, I would argue that the PC is rapidly becoming a niche product (at least for my generation) and since all smartphones run either FreeBSD/Darwin (iOS) or Linux (Android) with a PWA compatible browser, the primary platform to develop for definitely isn't Windows, but the web, and as for servers it's GNU/Linux for sure since a long time now, and LDK (Linux - Docker - Kubernetes) is the future for sure. In addition to that, doing anything else than primitive bash scripting isn't possible in WSL (which doesn't have anything to do with Linux, but GNU - thus the correct name should be GNU/NT) and thus the system is obsolete. Especially since using GNU/Linux/FreeBSD/Darwin is so easy now there really is no reason to use that legacy proprietary blob that literally preinstalls Candy Crush in 2018.

I do not disagree with you. :)

I agree with your rant but WSL is not as useless as you say. I work at a place where I have no option but use Win so I use WSL for multiple purposes and it works perfectly well for most of it. For instance, I'm just installing an ActiveMQ server in WSL. And I also use VS Code Remote with WSL wich is awesome.

VS Code Remote changes everything. So many things possible now

Hi. The etc/apt/apt.conf file is no longer there in the current version of WSL. Only apt.conf.d folder. No apt.conf file inside the apt.conf.d folder.

You can just create the file and add the line. Working for me now in 20.04
