Building vdsm repo fails in CI

Hi, when I try to build vdsm repo in Jenkins, it fails with ERROR: Command failed: 16:22:41 # /usr/bin/yum --installroot /var/lib/mock/epel-8- ppc64le-873106fe041e712f3fe68fbbfa530ba7-bootstrap-5067/root/ --releasever 8 install dnf dnf-plugins-core distribution-gpg-keys --setopt=tsflags=nocontexts 16:22:41 Failed to set locale, defaulting to C 16:22:41 Error: Package: python3-dnf-4.0.9.2-5.el8.noarch (centos-base-el8) 16:22:41 Requires: python3-libdnf >= 0.22.5-3 see e.g. [1]. Could someone take a look? It blocks any OST testing. Thanks Vojta [1] https://jenkins.ovirt.org/job/vdsm_standard-check-patch/13877/consoleFull
