Description

Currently, CI seems to fail consistently on the following jobs:

• ci/prow/images
• ci/prow/e2e-aws

The failure in both jobs is

http://vault.centos.org/centos/7/updates/Source/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
[ERROR] hack/build-rpms.sh:31: yum-builddep -y "${OS_RPM_SPECFILE}" exited with status 1.

(for complete log, see e.g. https://storage.googleapis.com/origin-ci-test/pr-logs/pull/cri-o_cri-o/4350/pull-ci-cri-o-cri-o-master-e2e-aws/1327016934725652480/build-log.txt)

and it is coming from here:

The failure seems to be related to the fact that vault.centos.org removed repodata directory from http://vault.centos.org/centos/7/updates/Source/ (note it's still available on a mirror, e.g. https://archive.kernel.org/centos-vault/centos/7/updates/Source/repodata/).

More importantly, it's not quite clear why we're still using centos 7.

Steps to reproduce the issue:

1. create a PR against cri-o/cri-o repo
