Hi all,Just for your info:the solution was:su - c "yum downgrade tripleo-ansible.noarch"yum list | grep -i tripleo-ansible
tripleo-ansible.noarch 0.4.1-1.el7 @centos-openstack-train
tripleo-ansible.noarch 0.5.0-1.el7 centos-openstack-trainWhat is wrong with tripleo-ansible.noarch 0.5.0-1.el7 centos-openstack-train ???
