What OS are you installing on? It looks like you're not running OctoPrint from a virtual environment. If you do "pip freeze" from the command line in your OctoPrint folder, what version of pyopenssl, openssl and cryptography modules do you have installed?

This is due to the following:
pyca/cryptography#3392

You should be able to fix it by manually installing cffi and then trying pyOpenSSL again.

pip install --upgrade cffi
pip install --upgrade pyOpenSSL

pip install --upgrade pyOpenSSL returns some errors...:

Ah oh. Your cffi package got mangled. You've got the python from one version and the built stuff from another. Oof. It'll probably take a few tries to get this fixed up as I can't replicate your state here.

How about:

sudo apt-get update
sudo apt-get install python-cffi python-openssl

[nyco007]

Unfortunally, since pip install --upgrade cffi my OctoPrint is not starting anymore...

I figured out to uninstall the cffi 1.10.0 with sudo apt-get remove python-cffi and tired then sudo apt-get install python-cffi python-openssl as you proposed.
Now the installation worked without issues. Thanks!

[OptogeneticsandNeuralEngineeringCore]

Thanks a bunch, everyone. I followed these steps, but also ran into issue with my pip being messed up. So for others having issue, it may be cool to try:
sudo apt-get update

Then pip check pip with pip freeze. If error:
sudo apt-get remove --auto-remove python-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
pip freeze

Then
sudo apt-get remove python-cffi
sudo apt-get install python-cffi python-openssl

sudo reboot
???
Profit.

I had the same error output caused by that ciff package. I did all things mentioned above and more that I don't even recall. In the end, I manage to fix by removing ciff by an "apt-get remove python-cffi" and by "pip uninstall cffi". When I installed it as described above and then had no problems with the "cryptography" package as the error posted also above.

But now I still get the same "Could Not parse output from pip" error. Lookin at the log I found this:

Running setup.py install for Pillow: started
Command "/home/pi/OctoPrint/venv/bin/python -u -c "import setuptools, tokenize;file='/tmp/pip-build-s8d6RN/Pillow/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-MMy_K0-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/pi/OctoPrint/venv/include/site/python2.7/Pillow" failed with error code 1 in /tmp/pip-build-s8d6RN/Pillow/
Running setup.py install for Pillow: finished with status 'error'

I will try to find anything related to this particular error, any thoughts? i will keep searching a little further and post any update.

I am running Jessie.

I figured it out! Searching a little further the log I found this message:

I found this, python-pillow/Pillow#2163

It seems that I was missing libjpeg dependency. I installed it with:
sudo apt-get install libjpeg-dev
Finally:
sudo pip install pillow

I hope this helps. Should I post this as a new error? Thanks

@OptogeneticsandNeuralEngineeringCore your solution works for me on a orange pi zero
