This is new problem on F30 because on F29 it seems to be fine: $ rpm -q dnf dnf-yum yum dnf-4.0.9-2.fc29.noarch dnf-yum-4.0.9-2.fc29.noarch yum-3.4.3-518.fc29.noarch But on Fedora 30: # dnf install dnf-yum Last metadata expiration check: 0:04:22 ago on Thu 24 Jan 2019 03:42:19 AM Error: Problem: problem with installed package yum-3.4.3-518.fc29.noarch - package dnf-yum-4.0.10-1.fc30.noarch conflicts with yum provided by yum-3.4.3-518.fc29.noarch - conflicting requests I'm not sure what package is broken, but since yum doesn't seem to be changed (nor rebuilt for f30), I guess this is caused by some change in dnf-yum.
This can either be resolved by a change similar to https://github.com/rpm-software-management/dnf/pull/1209, or by dropping YUM-3. We strongly prefer the latter: https://pagure.io/koji/issue/1214

The problem is already resolved with dnf-4.2.5
