** Description changed:
+ [Impact]
+
+ * Ubuntu's pip doesn't read /etc/pip.conf, the upstream documented
+ configuration file location, instead it reads the alternate path:
+ /etc/xdg/pip.conf
+ * While the alternate path is documented, too, this will probably confuse
+ users.
+
+ [Test Plan]
+
+ # apt install python3-pip
+ # python3 -c "from pip._internal.configuration import
get_configuration_files; print('/etc/pip.conf' in
get_configuration_files()['global'])"
+
+ False = bug
+ True = expected behaviour
+
+ [Where problems could occur]
+
+ * It's possible that somebody is relying on this behaviour to target one
+ config file at Ubuntu's pip and another at upstream pip, but that does
+ seem far-fetched.
+ * The patch is from upstream, so we're not stepping into uncharted
+ territory.

+ [Original Bug Report]
+
The pip3-20.0.2 from python3-pip package, and also installed with
"python3 -m venv" (ensurepip module), ignores /etc/pip.conf.
Based on https://pip.pypa.io/en/stable/user_guide/#config-file the
/etc/pip.conf should work. Also it does work properly if original
pip-20.0.2 is reinstalled to a venv from PyPI.
Steps to reproduce:
1. Add special package index URL to /etc/pip.conf, for example
[global]
index-url = https://download.zope.org/ppix
2. Try to install a package from your special index
Expected result:
* Packages from your index are available.
Current result:
* Only PyPI packaged are available.

We are trying to use this functionality to provide a local cache of PyPI
using Artifactory - to speed-up creating virtual environments inside
short-lived Docker and lessen PyPI bandwidth.
We are working around this by copying the file to
~/.config/pip/pip.conf, but we'd like to make it work system-wide.
