Comment 13 for bug 2021908

On the proxy settings: looks like this is one case where we set the proxy variables in autopkgtest environment, but there's is a daemon involved (fwupd) with its own environment where proxy vars are not set (same situation we have e.g. with Docker).

I had a quick look at fwupd and apparently it uses GProxyResolver, which is a GLib thing. I'm not sure on how to manually configure an http/https proxy so that GProxyResolver will use it.
