3. Update an env with packages from the mos-updates repo
4. Follow the guide for the mos_mu util https://github.com/rkhozinov/mos_mu/blob/9.2/doc/usage_9x.md

ansible-playbook playbooks/mos9_prepare_env.yml -e '{"env_id":3}'

Ansible version:
ansible.noarch 2.2.0.0-4.el7 @epel

[Anton Chevychalov (achevychalov)]

Ansible 2.2.0 from EPEL was used on that installation.

There is a bug in upstream version of Ansible https://bugs.launchpad.net/fuel/+bug/1652247

So we have to use patched version created by Mirantis.

Please do not use EPEL and follow upgrade procedure.

[Ruslan Khozinov (rkhozinov)]

I've checked that, the issue wasn't reproduced with correct version of ansible.
