As discussed in https://pagure.io/dusty/failed-composes/issue/1518 , a recent selinux-policy package build broke Rawhide compose. The problem is this commit: https://src.fedoraproject.org/rpms/selinux-policy/c/46c51e1cb2c7ece4c50ee988034e3a0379dd2bf3?branch=master (from https://src.fedoraproject.org/rpms/selinux-policy/pull-request/15 ). It uses shell script in `%pretrans`. As explained at http://rpm.org/user_doc/lua.html , this is not valid: "The internal interpreter can run when there’s nothing at all installed yet, because it doesn’t need to be forked. Consider the initial install phase: before even /bin/sh is available to execute the simplest shell built-in commands, the shell’s dependencies will have to be installed. What if some of those need scriptlets? Internal Lua is the only thing that can reliably run in %pretrans. On initial system installation, there’s absolutely nothing in the environment where %pretrans scriptlets execute. This is a condition you cannot even detect with any other means: testing for existence of a file or directory would otherwise require a shell, which is not there." So, you can't do that. Please either convert the %pretrans uses to use RPM lua not shell script, or find a different way of doing this.
I went ahead and untagged this build so we can get a compose and until it's sorted out.
Adam, Kevin, I reverted it, and we'll rewrite it in lua in future. https://koji.fedoraproject.org/koji/buildinfo?buildID=1216659
