Hi,

  I am trying to install Openstack Essex following the instructions from
this link<http://docs.openstack.org/essex/openstack-compute/install/yum/content/compute-db-sync.html>
.
But I get an error as follows which is faced by quite a number of users
based on the comments.
But none of them are resolved.
 If anyone has any idea what may be the problem, please let me know. Thanks
The error is as follows as soon as i run the *db-sync comand *during nova
installation.
