Description of problem: i manually upgraded the clusterversion from 4.2.14 to 4.2.16 with the command oc adm upgrade --to-image=quay.io/openshift-release-dev/ocp-release@sha256:04b79afdbb41579e0f969bf23cdb16483dbfadbc09a6a0fec60b94328d68135a --allow-explicit-upgrade=true --force it upgraded successfully oc version Client Version: openshift-clients-4.2.2-201910250432-8-g98a84c61 Server Version: 4.2.16 Kubernetes Version: v1.14.6+8bbaf43 But after installation the kube-apiserver operator remains in degraded state and showing Reason: NodeInstallerDegradedInstallerPodFailed Message: NodeInstallerDegraded: 1 nodes are failing on revision 10: NodeInstallerDegraded: pods "installer-10-master-1.m3559ocp.lnxne.boe" not found
could you try a 4.2.12 -> 4.2.16 upgrade? 4.2.14 is not a supported release.
that worked, still a bit confused which versions are supported and which not.
> still a bit confused which versions are supported and which not. See [1] about presence in fast/stable channels being the sign of support. And that shows that 4.2.14 on s390x is not supported: $ curl -sH 'Accept:application/json' 'https://api.openshift.com/api/upgrades_info/v1/graph?channel=fast-4.2&arch=s390x' | jq -r '.nodes[] | select(.version | contains("4.2.14"))' ...no matches...
