Hello
As the subject says, I am trying to install StarlingX for testing purposes.
For this, I am using the Simplex installation. This is my localhost.yml file:

system_mode: simplex
distributed_cloud_role: none
region_name: 'RegionOne'
timezone: UTC
dns_servers:
  - 8.8.8.8
  - 8.8.4.4
external_oam_subnet: 10.10.10.0/24
external_oam_gateway_address: 10.10.10.1
external_oam_floating_address: 10.10.10.111
admin_username: admin
admin_password: St8rlingXCloud*
wipe_ceph_osds: false
enable_volume_snapshot_support: true
add_docker_prefix: no
kernel: standard

The bootstrap finishes ok:

but when I try to unlock the controller-0 I get this error:

 [sysadmin@localhost ~(keystone_admin)]$ system host-unlock controller-0
unsupported operand type(s) for *: 'NoneType' and 'NoneType'

Can you help me, I am very new on this and I do not know even where to look for these errors.
Thank you.
