Errors during downloading metadata for repository 'http_kojipkgs_fedoraproject_org_repos_rawhide_latest_basearch':
  - Status code: 404 for https://kojipkgs.fedoraproject.org/repos/rawhide/latest/s390x/repodata/7ea5d60a860c857599e3ea6a936272eae2e76e7e0ef6a3d71948120ebc2c93da-primary.xml.gz (IP: 38.145.60.21)
Error: Failed to download metadata for repo 'http_kojipkgs_fedoraproject_org_repos_rawhide_latest_basearch': Yum repo downloading error: Downloading error(s): repodata/7ea5d60a860c857599e3ea6a936272eae2e76e7e0ef6a3d71948120ebc2c93da-primary.xml.gz - Cannot download, all mirrors were already tried without succes]: [And here we see that the Koji buildroot repository had some (perhaps temporary) problems when the builder machine attempted to download metadata files.

This actually shouldn't happen.  See https://pagure.io/releng/issue/11870 for more info.]

Issue: Because the builder failed to download Koji buildroot metadata.
Resolution: Restart the build after several minutes; the remote Koji buildroot repository typically gets fixed itself automatically.
