Fixed In Version: python-paramiko-2.1.1-4.el7 Doc Type: Bug Fix
Doc Text:
python-paramiko has been using the python2-pyasn1 package, but did not depend on it. With new versions of python2-cryptography, python2-pyasn1 was not getting installed and this caused python-paramiko to malfunction. This bug was fixed by making python-paramiko depend on python2-pyasn1 explicitly.

Description Alfredo Moralejo 2018-03-21 18:30:02 UTC
Description of problem:

When using python-paramiko to build openstack-sahara-tests in RDO, we find following error:

Failed to import test module: sahara_tests.unit.scenario.test_base
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/unittest2/loader.py", line 445, in _find_test_path
    module = self._get_module_from_name(name)

    from pyasn1.type.univ import ObjectIdentifier
ImportError: No module named pyasn1.type.univ

Looking at code and spec file, it seems package is missing some requirements as python-pyasn1.


Version-Release number of selected component (if applicable):

python-paramiko-2.1.1-2.el7

How reproducible:

always

Additional info:

Note that, with the version of python-cryptography-1.7.2-1.el7_4.1 depends on python-pyasn1 so, python-paramiko get it installed indirectly, but newer vrsions of cryptography removed that dependency so python-paramiko is broken and needs to explicitely depend on it.
