Stream uses another yum/dnf variable called "stream" : See on a 8-stream : cat /etc/yum/vars/stream 8-stream grep mirrorlist /etc/yum.repos.d/CentOS-Stream-BaseOS.repo mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=BaseOS&infra=$infra That's the reason why even for CentOS Infra we have a specific {{ centos_version }} declared in our ansible inventories that was 8 and now by default is 8-stream for the kickstart we use : https://github.com/CentOS/ansible-infra-playbooks/blob/master/templates/kickstarts/centos-8-ks.cfg.j2#L6 -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab -------------- next part -------------- A non-text attachment was scrubbed...
