Congratulations! One of the builds has completed. :champagne:

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/containerbuildsystem-koji-containerbuild-180
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.
