Change line #149 of the /usr/lib/python2.7/site-packages/rhn/SSL.py file

from :-

 # for Python 2
        else:
            if self._connection.state_string() == 'SSL negotiation finished successfully':
                self._connection.shutdown()

to :-

# for Python 2
        else:
            if self._connection.get_state_string() == 'SSL negotiation finished successfully':
                self._connection.shutdown()

Root Cause

  • This issue is caused due to some discrepancies between the python-pyOpenSSL and the rhnlib packages.
