[Rdo-list] Packstack error

Any ideas how to fix ? I'm running Scientific Linux 6.5. Running packstack (turning off neutron) ERROR : Error appeared during Puppet run: 128.142.135.93_horizon.pp Error: Parameter name failed on Package[horizon-packages]: Name must be a String not Array at /var/tmp/packstack/805bcb724cfe4f8499e799d1795f3a0c/manifests/128.142.135.93_horizon.pp:7 You will find full trace in log /var/tmp/packstack/20131220-135003-LzYOG0/manifests/128.142.135.93_horizon.pp.log The additional logs just report the same thing (i.e. Name must be a String not Array). cd /usr/lib/python2.6/site-packages/packstack/puppet/modules tar --dereference -cpzf - apache ceilometer certmonger cinder concat firewall glance heat horizon inifile keystone memcached mongodb mysql neutron nova nssdb openstack packstack qpid rsync ssh stdlib swift sysctl tempest vcsrepo vlan vswitch xinetd | ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root(a)128.142.135.93 tar -C /var/tmp/packstack/805bcb724cfe4f8499e799d1795f3a0c/modules -xpzf - 2013-12-20 13:52:12::ERROR::run_setup::909::root:: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/packstack/installer/run_setup.py", line 904, in main _main(confFile) File "/usr/lib/python2.6/site-packages/packstack/installer/run_setup.py", line 573, in _main runSequences() File "/usr/lib/python2.6/site-packages/packstack/installer/run_setup.py", line 552, in runSequences controller.runAllSequences() File "/usr/lib/python2.6/site-packages/packstack/installer/setup_controller.py", line 84, in runAllSequences sequence.run(self.CONF) File "/usr/lib/python2.6/site-packages/packstack/installer/core/sequences.py", line 105, in run step.run(config=config) File "/usr/lib/python2.6/site-packages/packstack/installer/core/sequences.py", line 52, in run raise SequenceError(str(ex)) SequenceError: Error appeared during Puppet run: 128.142.135.93_horizon.pp Error: Parameter name failed on Package[horizon-packages]: Name must be a String not Array at /var/tmp/packstack/805bcb724cfe4f8499e799d1795f3a0c/manifests/128.142.135.93_horizon.pp:7 You will find full trace in log /var/tmp/packstack/20131220-135003-LzYOG0/manifests/128.142.135.93_horizon.pp.log [cid:image001.png@01CEFD89.483D8020]
