detach-database plugin can't be uninstall from Fuel (MOS9)

Hi,

I am trying to uninstall detach-database plugin from fuel master but it is showing error "Error in PREUN scriptlet in rpm package detach-database-1.1-1.1.0-1.noarch". To remove this plugin and make it re-install, have to delete the rpm with rpm -e option.

Plugin: https://github.com/openstack/fuel-plugin-detach-database.git

Please find all execution below.
