Openstack tripleo install fails

I have been trying to install OpenStack on a CentOS 7 system following the instructions in https://docs.openstack.org/tripleo-docs/latest/install/installation/installation.html Using the command sudo yum install -y https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-.el7.centos.noarch.rpm I am let to believe that should be something of "queens" or "pike" etc. But I get the following result: [stack@pallas ~]$ sudo yum install https://trunk.rdoproject.org/centos7/python2-tripleo-repos-queens.el7.centos.noarch.rpm Loaded plugins: fastestmirror, versionlock Cannot open: https://trunk.rdoproject.org/centos7/python2-tripleo-repos-queens.el7.centos.noarch.rpm. Skipping. Error: Nothing to do Am I doing something wrong?
