Wenkai Shi, can you provide your inventory file for reference please? > 2. Install env on it(1 master 2 nodes), with parameter "openshift_image_tag" What are you setting the "openshift_image_tag" value to?

And I change it to v3.4.0.38 on "3. update parameter and run upgrade playbook". Please let me know if you need other parameter.
Commit pushed to master at https://github.com/openshift/openshift-ansible https://github.com/openshift/openshift-ansible/commit/3cc4232e756d0f0c0abbe97129598aeac593c75d Don't upgrade etcd on atomic host, ever. Fixes Bug 1408668 Fixes BZ1408668
The cryptic error message is because ansible cannot find a package manager on atomic host. So the fix is to never attempt to upgrade etcd on atomic host. https://github.com/openshift/openshift-ansible/pull/3046
Verified with openshift-ansible-3.4.43-1.git.0.a9dbe87.el7.noarch, upgrade succeed.
