Start with the rhcos.upgrade.from-ocp-rhcos test and upgrade.go, focusing on the verify-no-pkg-downgrades failure. Review the reported skopeo versions and the referenced artifact URL, then rerun the test after identifying the outdated package source. Done means the upgrade test no longer reports a skopeo downgrade.
