[rdo-users] Failed to install undercloud Train on CentOS 8

[wodel youchi]

Hi,
I am trying to install the undercloud using the Train version on CentOS 8
Stream.
I am using container-tools 3.0

I have installed :
*yum install  -y python3-tripleoclient ceph-ansible *

And I am not using any external authentication (no IPA)
I am getting this error message upon deployment
