Hi Folks , I am trying to install 3 node openstack newton on CentOS 7 using packstack. But getting below error. In the answer file i have mentioned that packstack script will create selfsign certificate at the mentioned location. Preparing Nova VNC Proxy entries [ ERROR ] ERROR : [Errno 2] No such file or directory: '/etc/pki/tls/certs/selfcert.crt' ~]# tail -f /var/tmp/packstack/20161008-104443-u_wbaC/openstack-setup.log File "/usr/lib/python2.7/site-packages/packstack/modules/ospluginutils.py", line 101, in generate_ssl_cert ca_file = open(config['CONFIG_SSL_CACERT_FILE'], 'rt').read() IOError: [Errno 2] No such file or directory: '/etc/pki/tls/certs/selfcert.crt' 2016-10-08 10:56:33::INFO::shell::94::root:: [192.168.43.70] Executing script: rm -rf /var/tmp/packstack/8a47dc48454c40a0a8c7856728604812 2016-10-08 10:56:34::INFO::shell::94::root:: [192.168.43.80] Executing script: rm -rf /var/tmp/packstack/844988cf4be74a6cb5b95a22c7eab220 2016-10-08 10:56:34::INFO::shell::94::root:: [192.168.43.90] Executing script: rm -rf /var/tmp/packstack/d2e704b6b353457aac455dca91efc2d6 Any idea how to resolve this issue so that i can latest version of openstack. It also seems to be a bug in the script. -- Best Regards Pradeep Kumar
