Package: python-pip-whl
Version: 9.0.1-2
Severity: normal
Dear Maintainer,
when trying to install a package with pip and the PyPI index server is
unavailable,
urllib3 raises an error.
I ran into this issue when using an extra-index-url option pointing to a server
that was down.
For example:
$ pip install pyyml
Collecting pyyml
Exception:
Traceback (most recent call last):

The expected behavior would be that pip logs a warning and fails gracefully,
e.g.
$ pip install pyyml
Collecting pyyml
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after
connection broken by
'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.HTTPConnection

Could not find a version that satisfies the requirement pyyml (from versions:
)
No matching distribution found for pyyml
Upstream references can be found e.g. at
https://github.com/shazow/urllib3/issues/567
As a workaround, using a more recent version of the "requests" wheel file in
/usr/share/python-wheels
fixes the problem. Additionally, one should also replace the "urllib3" and
"chardet" wheels so that
"requests" does not show warnings:
- requests: 2.18
- urllib3: 1.22
- chardet: 3.0.4
Thanks
