That's funny, we list python-glanceclient in OSC dependencies (https://github.com/openstack/python-openstackclient/blob/master/requirements.txt)

And glanceclient lists pyOpenSSL in it's requirements (https://github.com/openstack/python-glanceclient/blob/master/requirements.txt)

Lastly, pyOpenSSL requires the cryptography package: https://github.com/pyca/pyopenssl/blob/master/setup.py#L37

Also, how was this being installed? And which versions of openstackclient, python-glanceclient, and pyOpenSSL are installed?

[Ian Cordasco (icordasc)]

Hi Aaron,

Could you please tell us how and from where you installed the openstackclient?

[Ian Cordasco (icordasc)]

Could you run the following and let me know what happens as well:

python -c 'import cryptography; print(cryptography.__file__)'
python -c 'import cryptography.hazmat; print(cryptography.hazmat.__file__)'
python -c 'import cryptography.hazmat.bindings; print(cryptography.hazmat.bindings.__file__)'
python -c 'import cryptography.hazmat.bindings.openssl; print(cryptography.hazmat.bindings.openssl.__file__)'
python -c 'import cryptography.hazmat.bindings.openssl.binding; print(cryptography..hazmat.bindings.openssl.binding.__file__)'

If any of them fails, there's no need to try the rest.
