I did this

$curl https://github.com/rmarquis/pacaur/archive/4.6.9.tar.gz
curl: (7) Unsupported proxy scheme for 'https://xxx.xxx.xxx.xxx:80'

$export | grep https_proxy
https_proxy=https://xxx.xxx.xxx.xxx::80

I expected the following

$curl https://github.com/rmarquis/pacaur/archive/4.6.9.tar.gz
<html><body>You are being <a href="https://codeload.github.com/rmarquis/pacaur/tar.gz/4.6.9">redirected</a>.</body></html>

curl doesn't support HTTPS proxy so you get this message to make you aware of that so that you don't think you're actually are using a HTTPS proxy.

Previously curl would just ignore non-supported schemes in the proxy URL and that mislead people into believing things about what they accomplished. Now, curl will tell you when you try to use a proxy method that curl doesn't support. Like HTTPS.

If you instead specify http:// to the proxy, you'll see that it works (like before) and you don't any longer rely on curl's silent downgrade.

https_proxy=http://xxx.xxx.xxx.xxx::80 works! Thx...

cURL (>=7.52.0) supports HTTPS proxies https://daniel.haxx.se/blog/2016/11/26/https-proxy-with-curl/

@mrtazz
change prefixed address for proxy to HTTP 
curl doesn't support https proxies prior to version 7.52.0. It used to
silently drop it but in newer versions below 7.52.0 it fails with

curl: (7) Unsupported proxy scheme for 'https://xxx.xxx.xxx.xxx:80'

Since this unit test just makes sure the code parsing the prefix gets
executed properly, we can change it to http here and get the same
effect.

@sponiasmona if you experience a bug with the latest curl, file a new bug. This is an old and closed report.
