Failing payload: https://amd64.ocp.releases.ci.openshift.org/releasestream/4.22.0-0.nightly/release/4.22.0-0.nightly-2026-01-23-043833
: [sig-builds][Feature:Builds] Optimized image builds should succeed [apigroup:build.openshift.io] [Suite:openshift/conformance/parallel]
Failures have this in stdout:
STEP 1/6: FROM image-registry.openshift-image-registry.svc:5000/openshift/tools:latest STEP 2/6: ENV "BUILD_LOGLEVEL"="2" STEP 3/6: RUN yum list installed This is microdnf, which implements subset of `dnf'. ... error: Unknown command: 'list'
So the culprit is likely migration to minimal images with microdnf, reported in https://redhat-internal.slack.com/archives/C01CQA76KMX/p1769169261322869
