I've just installed a blank Fedora Rawhide on a Virtual Machine under VirtualBox. When I try to execute 'dnf list --installed <whatever>' I always get 'ArgumentError: argument --obsoletes: conflicting option string: --obsoletes' I'm using dnf-2.0.1-2.fc26. I see in Koji a newer dnf-2.1 but running dnf upgrade doesn't find it.
