Environment

Python 2.7.12
NetBox version: v2.1.5 Upgrading to Release v2.2.1

Steps to Reproduce:

Install Netbox and a system that has FreeIPA client installed.

$ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import paramiko
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/paramiko/__init__.py", line 31, in <module>
    from paramiko.transport import SecurityOptions, Transport
  File "/usr/local/lib/python2.7/dist-packages/paramiko/transport.py", line 38, in <module>
    from paramiko.auth_handler import AuthHandler
  File "/usr/local/lib/python2.7/dist-packages/paramiko/auth_handler.py", line 48, in <module>
    from paramiko.ssh_gss import GSSAuth, GSS_EXCEPTIONS
  File "/usr/local/lib/python2.7/dist-packages/paramiko/ssh_gss.py", line 54, in <module>
    GSS_EXCEPTIONS = (gssapi.GSSException,)
AttributeError: 'module' object has no attribute 'GSSException'
>>> exit()

The install works fine during pip package upgrades but errors out during manage.py migrate. It looks like this is due to the upgrade of python package paramiko to 2.3.1 and is referenced on Paramiko Bug 1069. The temporary workaround is to downgrade to paramiko==2.2.1 but I was unable to successfully run NetBox v2.2.1 using paramiko==2.2.1.

Relevant error:

I don't think this is something we can control, but thank you for documenting it. I'm hoping to rip out the legacy RPC stuff as soon as I can get inventory working via NAPALM, which should help avoid this kind of issue.
