Changing the priority as upgrading to v12.0.0 kubernetes would cause failure in user-api.
/priority important-soon
/lifecycle frozen
/triage accepted

Any upgrade of kubernetes and openshift version, should be tested in user-api as well.

• Install common in user-api
• Execute the user-api to check its functionalities.
• Also upgrade in package-extract: Pin kubernetes to ~=11.0.0 package-extract#501
