I have a script on python3.4 and it has been fine until the website I download the file from decides to use https and now I am getting error but can't figure out how I can retrive the file.

My script import the following library and uses the urlretrive to get the file previously. Since it is now forwarded to https with 302 redirection. I am getting some error.

import urllib
import urllib.request

urllib.request.urlretrieve("http://wordpress.org/latest.tar.gz", "/thefile.gz")

My error:-

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.4/urllib/request.py", line 178, in urlretrieve
    with contextlib.closing(urlopen(url, data)) as fp:

    return opener.open(url, data, timeout)

    response = meth(req, response)

Most likely your Python installation or operating system is broken.

Python has only support for HTTPS if it was compiled with HTTPS support. However, this should be the default for all sane installations.

HTTPS support is only available if the socket module was compiled with SSL support.

Please clarify how you installed Python. Official Python distributions are available at python.org
