hello sir When I have finished to run    ./fred-manager install all is ok but when I run:    ./fred-manager start sent back errors like:       Starting PostgreSQL failed!     Starting omniNames... failed!     -su: /home/nic/root/sbin/fred-dbmanager: Permission non accordée     Starting FRED central registry CORBA servers... failed!     Starting Apache....     Starting FRED webadmin HTTP server.... Is it the fact that those services were already runing ?                thank you
