I had to change hostname and IP of Red Hat Satellite 6 (/etc/hosts and /etc/hostname), but when I exec Katello Installer to update certificates the NSSDB stops with the following error:

Could someone tell me how to update the NSSDB certificate correctly or fix it? I stopped all services and tried to run installer again, but the error went on.

Thanks.
