el8 builds broken?

Zoneminder builds on el8 have been failing for me recently, with failure to init buildroot messages. The build complains some very basic packages are uninstallable such as: rpm, curl, git, gnupg2, etc. Full error log is here: http://koji.rpmfusion.org/kojifiles/work/tasks/6735/406735/root.log If I am looking at Koji right, the last successful el8 build, by anyone, was done by me on May 2, so something fairly recently has gone wrong.
