Hmm, may be getting stepped on.

Here we see it gets set:

Investigating...

This [1] is stomping status because what it's holding here [2] is obsolete.

What code-base was used for the comment 0 test?

Along the same lines as Trevor's question, how was this tested? How did you get the system installed with capabilities "None" such that you could change it to v4.11? I was trying to test my fix by overwriting the capabilities setting to None but my cluster fails to start because of issues with marketplace-operator-metrics resources.

To answer my own question, I suppose you were simply using the Installer and selected "None". My problem was that I was using cluster bot and changing the setting after install in the CVO code as a "test-only" hack.

(In reply to W. Trevor King from comment #3)

> What code-base was used for the comment 0 test?

The payload I was using was built from cvo#754 by using cluster-bot

build openshift/cluster-version-operator#754

I installed the cluster with baselineCapabilitySet: None. The CVO did loop on the service "openshift-marketplace/marketplace-operator-metrics" creation [1]. But the cluster was functional after installation exited.

For your testing, I feel we can install a cluster with below cap set to workaround the marketplace-operator-metrics issue. And then change the baseline to v4.11.

spec:
    capabilities:
      additionalEnabledCapabilities:
      - marketplace
      baselineCapabilitySet: None

Retried nightly builds and faced it with 4.11.0-0.nightly-2022-04-01-172551 and didn't face it with 4.11.0-0.nightly-2022-04-06-000911. Hmm, possibly it's affected by https://bugzilla.redhat.com/show_bug.cgi?id=2070792.

Starting a 4.11.0-0.nightly-2022-04-01-172551 cluster with baselineCapabilitySet: None and then modify it to v4.11, then we have:
