Hi, We have a roadblock with the OpenStack Pike Installation during the installation of packstack using the answers file generated. We are facing the below error, [opsmxuser@centos7open ~]$ sudo packstack --answer-file=/home/OpenStack/OpenStack.conf Welcome to the Packstack setup utility

The installation log file is available at: /var/tmp/packstack/20180925-205256-CiTSew/openstack-setup.log

Installing: Clean Up [ DONE ] Discovering ip protocol version [ DONE ] Setting up ssh keys [ DONE ] Preparing servers [ ERROR ]

ERROR : Failed to run remote script, stdout: stderr: Warning: Permanently added '<ip_address>' (ECDSA) to the list of known hosts. Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

Please check log file /var/tmp/packstack/20180925-205256-CiTSew/openstack-setup.log for more information Additional information:

* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.

I have already referred to the below article, but of no luck https://ask.openstack.org/en/question/83200/packstack-fails-during-setting-up-ssh-key/ (https://ask.openstack.org/en/question...)

Request anyone kindly assist us in fixing the issue.

Thanks in Advance for your Assistance.
