The build is failing because openssl-3.0.7 is no longer available in the main Centos Stream 9 repositories. You would need to modify the dockerfile template to add rpm repos pointing to an archive mirror, or modify the install command to use openssl-3.2.1 or newer (which may lead to further build errors if there’s hard dependency on 3.0.7).
@chrisl The devel branch is being overhauled and split into plugins (plugins-docs), and other components that may exist in other repos. As a result, the main repo will appear to be missing things, but that is by design. That said, I don’t know how you’re supposed to build devel now.
