実行するとyum install openssl-devel依存関係チェックエラーが発生するため、インストールしないでください。リポジトリに問題があるようですが、インストールしたCentOSバージョン（）に何が問題なのかわかりませんが、通常はLinux release 7.5.1804パラメータを使用してyumを実行する必要があります--skip-broken。私のリポジトリの優先順位を設定する必要があると思います。

You could try using --skip-broken to work around the problem

答え1
RPM DB または YUM が互いにまたはアップストリームと同期していないか、同期していないようです。
私は次のことをします：
$ sudo yum clean all
$ sudo yum update -y
それでもうまくいかない場合は、同期していないYUMリポジトリにRPMがインストールされていないことを確認してください。パッケージが何度もインストールされていることがよく見られます。
$ sudo rpm -qa | grep -i 'dracut'
この場合、同じ名前の2つのプロジェクトが表示されます。この問題を解決するには、通常は削除しますが、これは難しい場合があります。次のことを試すことができます。
$ sudo yum reinstall <pkg>
