[ovirt-devel] Error in running engine-setup

I am having a issue in running $HOME/ovirt-engine/bin/engine-setup. Earlier I was getting this error [ ERROR ] Failed to execute stage 'Misc configuration': [Errno 13] Permission denied: '/var/lib/pgsql/data/postgresql.conf' then I just change the permission of /var/lib/pgsql/data/postgresql.conf and /var/lib/pgsql/data/ * to 777 now I am getting this error [ ERROR ] Failed to execute stage 'Misc configuration': [Errno 1] Operation not permitted: '/var/lib/pgsql/data/postgresql.conf.20170719001357' So, any solution for that? Thanks, Shubham
