#567: python2 update required
Reporter:  ndawson  |      Owner:  osgeo4w-dev@…
    Type:  defect   |     Status:  new
Priority:  major    |  Component:  Package
 Version:           |   Keywords:  python
 The current version of Python 2 in osgeo4w (2.7.4) is no longer compatible
 with the pip repository - trying to run pip install under osgeo4w python
 results in errors "SNIMissingWarning: An HTTPS request has been made, but
 the SNI (Subject Name Indication) extension to TLS is not available on
 this platform." and "Could not fetch URL
 https://pypi.python.org/simple/pint/: There was a problem confirming the
 ssl certificate: [Errno 1] _ssl.c:504: error:1407742E:SSL
 routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version - skipping
 Could not find a version that satisfies the requirement pint (from
 versions: )"

 As a result it's no longer possible to install Python2 packages using pip
 on osgeo4w. There's no reliable workarounds which users can do to avoid
 this - the only solution is to update the Python library to a more recent
