Overcloud deployment with the rhsm composable service that uses activation key and 'autosubscribe: no' fails with: "msg": "parameters are mutually exclusive: activationkey, autosubscribe"
[heat-admin@osp13-controller1 ~]$ rpm -q ansible-role-redhat-subscription
ansible-role-redhat-subscription-1.0.4-1.el7ost.noarch
This version is greater than the one that had the solution for bug 1640652
The right fix is to remove rhsm_autosubscribe from your config. Like the error says, this option isn't compatible when using an activation key.
The fix that we provided in zstream just changed the default: https://review.opendev.org/#/c/611334/3/defaults/main.yml but it's up to you to remove that "rhsm_autosubscribe: no".
I'm closing that bug, please re-open if you still encounter the issue.
