    I cannot seem to get the following command to complete:

    [root@cloud ~]# packstack --answer-file 04.11.16.conf
    ERROR : [Errno 2] No such file or directory: '/etc/pki/tls/certs/selfcert.crt'

    Then I got:

    ERROR : [Errno 2] No such file or directory: '/etc/pki/tls/private/selfkey.key'

    I am assuming that I am missing a critical piece to the installation. Perhaps something that is done even before this tutorial can be followed. I tried to follow the following link to fix the certificate issue:

    Can you help me figure out what is missing and get through the rest of the install?

    Need Help..

    After executing the command "packstack –answer-file 13.04.16.conf" the process asked me for password just after the line "Setting up SSH Keys"
    Please suggest me how to proceed

      Hi Omkar,

      To the best of my knowledge, It will let you to setup a password and this it will ask for each service and DB.

      I think this because of some recent update in openstack-packstack… not sure..
