Hi,

I am using Wallaby.

Using this documentation (https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/deployment/install_overcloud.html#deploy-the-overcloud), I am trying to build the overcloud images like this :

export OS_YAML="/usr/share/openstack-tripleo-common/image-yaml/overcloud-images-centos8.yaml"
export DIB_YUM_REPO_CONF="/etc/yum.repos.d/delorean* /etc/yum.repos.d/tripleo-centos-*"
export STABLE_RELEASE="wallaby"
openstack overcloud image build --config-file /usr/share/openstack-tripleo-common/image-yaml/overcloud-images-python3.yaml --config-file $OS_YAML

But I got these errors at the end :

...

What did I miss?
