This is a clone of issue
OCPBUGS-4700. The following is the description of the original issue:
Description of problem:
In at least 4.12.0-rc.0, a user with read-only access to ClusterVersion can see an "Update blocked" pop-up talking about "...alert above the visualization...". It is referencing a banner about "This cluster should not be updated to the next minor version...", but that banner is not displayed because hasPermissionsToUpdate is false, so canPerformUpgrade is false.
Version-Release number of selected component (if applicable):
4.12.0-rc.0. Likely more. I haven't traced it out.
Steps to Reproduce:
1. Install 4.12.0-rc.0
2. Create a user with cluster-wide read-only permissions. For me, it's via binding to a sudoer ClusterRole. I'm not sure where that ClusterRole comes from, but it's:
3. View /settings/cluster
See the "Update blocked" pop-up talking about "...alert above the visualization...".
Something more internally consistent. E.g. having the referenced banner "...alert above the visualization..." show up, or not having the "Update blocked" pop-up reference the non-existent banner.
