yum clean all gives multiple string errors

When I am trying to connect instance to Satellite Server it's failing. I tried to perform basic system updates and tried running yum clean all. However, I am getting following lines: Traceback (most recent call last): File "/usr/bin/yum", line 29, in yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 300, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 115, in main base.getOptionsConfig(args) File "/usr/share/yum-cli/cli.py", line 229, in getOptionsConfig self.conf File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 911, in conf = property(fget=lambda self: self._getConfig(), File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 363, in _getConfig self.plugins.run('init') File "/usr/lib/python2.6/site-packages/yum/plugins.py", line 184, in run func(conduitcls(self, self.base, conf, **kwargs)) File "/usr/share/yum-plugins/ulninfo.py", line 23, in init_hook login_info = up2dateAuth.getLoginInfo(timeout=timeout) File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 219, in getLoginInfo login(timeout=timeout) File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 167, in login if readCachedLogin(): File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 133, in readCachedLogin expireTime = float(li['X-RHN-Auth-Expiration']) KeyError: 'X-RHN-Auth-Expiration' Can someone throw some light on this?
