Comment 2 for bug 1825111

Thanks for your response, but I'm not entirely with you, I'm sorry.

Keystone 15.0.0 is the current version, corresponding to Openstack Stein -> https://docs.openstack.org/releasenotes/keystone/stein.html

After updating and upgrading the new Ubuntu 18.04.2 I added the repository Stein (add-apt-repository cloud-archive: stein).

What about the following question: Can I install a first system directly with the Stein release, or do I have to install Queens and then migrate to Stein via Rocky?
