I have installed the paramiko module. However, when I tried to import that module. I got the following error.

import paramiko
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     31 from paramiko.client import SSHClient, MissingHostKeyPolicy, AutoAddPolicy, RejectPolicy, WarningPolicy
     32 from paramiko.auth_handler import AuthHandler

     33 from paramiko.auth_handler import AuthHandler
     34 from paramiko.ssh_gss import GSSAuth

ImportError: cannot import name util

Does anyone know how to resolve this issue?

  • Which command did you use to install paramiko? – narendranathjoshi Oct 26 '15 at 09:35

    Just checked on a Linux install, and /usr/lib/python2.7/dist-packages/paramiko/transport.py has the same line (but at 33). This "cannot import name" error often relates to circularly dependent imports, but paramiko doesn't typically have that problem itself (see http://stackoverflow.com/questions/9252543/importerror-cannot-import-name-x for an example). Which version of python? Are you importing other things before your example? – Alex North-Keys Aug 08 '16 at 06:32
  • Was this resolved? I'm having the same issue with python 2.7.6 – Josh C. Dec 20 '16 at 18:00

I have just had the same issue myself (python 2.7.6), and ran into this answer here ImportError: Cannot import name X , which was referred in the question's comments, suggesting it's a circular dependency issue.

After not finding any elegant solution I found myself editing paramiko's source code in site-packages/paramiko/transport.py:

  • Comment / remove the line from paramiko import util
  • Replace every occurrence of util (in this file) to paramiko.util
  • Be careful while replacing: DO NOT replace existing occurrences of paramiko.util

This had fixed the problem for me, leaving me somewhat confused: on the one hand, modifying the import method seems to solve this, but on the other hand Python deals with it in like... 99% of the cases..? Awkward.

We can just edit the import line to be:

from . import util

So we don't have to change every occurrence.

It is strange that after fixing this in paramiko 2.4, I have another import error, which is:

> python
Python 2.7.5 (default, Aug  4 2017, 00:39:18)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] 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/lib/python2.7/site-packages/paramiko/__init__.py", line 22, in <module>
    from paramiko.transport import SecurityOptions, Transport
  File "/usr/lib/python2.7/site-packages/paramiko/transport.py", line 38, in <module>
    from paramiko.auth_handler import AuthHandler
  File "/usr/lib/python2.7/site-packages/paramiko/auth_handler.py", line 48, in <module>
    from paramiko.ssh_gss import GSSAuth, GSS_EXCEPTIONS
  File "/usr/lib/python2.7/site-packages/paramiko/ssh_gss.py", line 54, in <module>
    GSS_EXCEPTIONS = (gssapi.GSSException,)
AttributeError: 'module' object has no attribute 'GSSException'

It turns out that I have somehow installed cyrus-sasl-gssapi which has the module gssapi but without GSSException. So python is confused. I removed the package and all is fine. If you have python-gssapi, be sure to remove that, too.

It is an issue of paramiko(#1069). But not fixed in paramiko 2.4 for Python 2.7. Have reported it.

Try with reinstalling it. In my case, it works.

pip uninstall paramiko
pip install paramiko --upgrade

My method is Download python utils from here https://pypi.org/project/utils/#files，and pip install utils-0.9.0-py2.py3-none-any.whl， the problem has been resolved。I think the real cause is without the lib utils。

Just to add to Kludge's answer, we will need to replace "util" with paramiko.util" in each of the following files: transport.py, dsskey.py, ber.py, pkey.py, kex_gex.py, kex_group1.py, kex_gss.py, packet.py, primes.py, sftp_client.py, sftp.py, sftp_server.py.

Quoting Kludge's method for better clarity:

  • Comment / remove the line from paramiko import util
  • Replace every occurrence of util (in this file) to paramiko.util
  • Be careful while replacing: DO NOT replace existing occurrences of paramiko.util
