Description
What went wrong?
The new 1.6.4 release dropped support for Python 2.7 and 3.5 which is fine but when a user goes to pip install gssapi on those hosts it will install 1.6.4 when 1.6.2 should really be the one to install.
I'm not sure if we can actually do anything for this now a release is out but it would be good to avoid this in the future when a Python version is dropped. IIRC to do this you just need to add python_requires to setup.py which is what Ansible is doing https://github.com/ansible/ansible/blob/148e83f832aafa27bb49e98667bdcf72f1fd0f84/setup.py#L277. For this project it should be python_requires=">=3.6.*"
How do we reproduce?
pip install gssapi on a Python 2.7 or 3.5. The install works fine but when you go to use the library 3.6 specific syntax will cause a failure. Ideally a pip install on those version should select the latest version that is supported for that Python version.
Component versions (python-gssapi, Kerberos, OS / distro, etc.)
Install through pip on Python 2.7 and/or 3.5.
