Similar erri=or is raised in the case of upgrading any package. Is it a problem with pip or requests module or urllib3. Can anyone suggest a fix.

[rbtcollins]

That error is being thrown within the pip vendored code, so I'd say a pip issue.

What platform, Python version are you using?

[rbtcollins]

Also what pip version?

[raj454raj]

@rbtcollins : Thanks for you reply. Python 2.7.7 Pip 1.5.6 Any help?

[rbtcollins]

Hi sorry.

So - I'd suggest you try pip 6.1.1 as a first step. Thats quite a bit newer, and may include a fix.

[raj454raj]

Hey @rbtcollins. Again the same error pops up when installing pip with python get-pip.py

Is there a way to get rid of pip completely and then start from scratch. PS: I am using Ubuntu 14.04 under proxy network I tried this also

python get-pip.py --proxy="http://proxy.iiit.ac.in:8080/

and

pip install -U pip

which leads to same traceback

[rbtcollins]

Try this:

• download the pip wheel from pypi using your browser
• install it using: pip install --no-index ./path/to/pip/wheel.

[raj454raj]

Hey @rbtcollins sorry but I didn't understand the first part

[nwork]

I was able to correct this error by upgrading pyOpenSSL

[raj454raj]

@nwork : How did you upgraded pyOpenSSL since I get the error while upgrading by pip also. Please I urgently need to fix this issue.

[nwork]

via their github page https://github.com/pyca/pyopenssl

[raj454raj]

@nwork : Tried a lot no good still. Github page suggests pip install pyopenssl - which gives me requirement satisfied and on --upgrade it gives me -

Cannot fetch index base URL https://pypi.python.org/simple/ Could not find any downloads that satisfy the requirement pyopenssl in /usr/local/lib/python2.7/dist-packages Downloading/unpacking pyopenssl Cleaning up... No distributions at all found for pyopenssl in /usr/local/lib/python2.7/dist-packages Storing debug log for failure in /home/raj/.pip/pip.log

Please help me !!!

[nwork]

I just downloaded the zip via the browser.. cd extractedDir sudo python setup.py install

[dstufft]

Hmm, I think this is another one that either @sigmavirus24 or @lukasa would have insight on, I think this is a urllib3 problem.

[Lukasa]

Looks like an old version of PyOpenSSL is installed, which is missing set_tlsext_host_name. That means it's a version lower than 0.13. Consider upgrading. =)

[Lukasa]

Separately, requests should probably version check pyopenssl before we inject it. Thoughts @sigmavirus24?

[dstufft]

Ok, I'm going to close this issue then since @Lukasa thinks it's just an old PyOpenSSL. Thanks!

[sigmavirus24]

@Lukasa I'm okay with that. We should probably discuss that on a requests issue though

[raj454raj]

I am not able to upgrade my pyopenssl and hence the problem still remains

[sigmavirus24]

@raj454raj try uninstalling pyOpenSSL first

[kaos]

After upgrading pyOpenSSL I still have this issue. If I uninstall ndg-httpsclient, it goes away, but then I get a warning that a true SSL context object is not available, ssl is unusable.

/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

Not sure what is wrong, since I have a subset of the same set of packages/versions in another installation that works fine (although, that is a CentOS 6, while the one with issues is a RedHat 6, but still), with ndg-httpsclient present (and ssl working).

[kaos]

Solved it by running yum remove pyOpenSSL (somehow the older version from yum messed up the installation.. :p)

[rasselin]

We ran into this. We had to apt-get uninstall python-openssl (0.12), after which we're able to pip install pyOpenSSL (0.15.1) which resolves the issue.

[inetfuture]

apt-get remove python-openssl works for me.
