我最近从Fedora 20升级到Fedora 21.我在尝试安装或更新时面临依赖性问题：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我尝试禁用/启用一些存储库，试图更新，试图删除上面列出的一些库，但全部徒劳无功。
摆脱 rpmfusion-free-rawhide repo，它适用于未发行的fedora 22.应该解决所有问题。
在我的情况下，罪魁祸首是rpmfusion。我有不同版本的无RPMFusion-Free和RPMFusion-Nonfree。其中一个是21，另一个是22岁。因此，删除和安装正确的版本如下解决了：
sudo yum remove rpmfusion-free-release rpmfusion-nonfree-release
