Description of problem:

Issue in self-managed platform
Agent - Bare Metal

In the UI, under distribution version there is no "Upgrade available" link. If I access the upgrade menu from the three dots menu, it says there are no available upgrades.

The HCP is using OCP 4.18.4-multi release, and there should be upgrades to 4.18.7 and 4.18.8.

The management cluster is running 4.18.4-x86 release.

I also tried to set hostedcluster.spec.channel to 'stable-4.18', but still no luck.

I could start the upgrade by patching the hostedcluster.spec.release directly.

There are clusterimagesets available for the named releases:

$oc get clusterimageset  | grep 4.18.[7-8]

img4.18.7-multi-appsub     quay.io/openshift-release-dev/ocp-release:4.18.7-multi
img4.18.7-x86-64-appsub    quay.io/openshift-release-dev/ocp-release:4.18.7-x86_64
img4.18.8-multi-appsub     quay.io/openshift-release-dev/ocp-release:4.18.8-multi
img4.18.8-x86-64-appsub    quay.io/openshift-release-dev/ocp-release:4.18.8-x86_64

Version-Release number of selected component (if applicable):

MCE 2.8
OCP 4.18

How reproducible:

Always

Steps to Reproduce:

1. Deploy a HostedCluster with agent provider
2. Access the MCE UI and check for available upgrades (there won't be a link to upgrade cluster)

Actual results:

No upgrade link available.

Expected results:

Upgrade link available.
