运行yum install openssl-devel会导致依赖性检查错误，请勿安装。我猜我的存储库有问题，但我不知道我安装的 CentOS 版本有什么问题（Linux release 7.5.1804），但我通常需要使用--skip-broken参数运行 yum。我想我应该为我的存储库设置优先级。
这是内容CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the

# If the mirrorlist= does not work for you, as a fall back you can try the

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

答案1
似乎您的 RPM DB 或 YUM 彼此或其上游不同步和/或不同步。
我会做以下事情：
$ sudo yum clean all
$ sudo yum update -y
如果事情看起来仍然挂起，请检查以确保您没有安装来自不同步的 YUM 存储库的 RPM。您通常会看到软件包安装了多次：
$ sudo rpm -qa | grep -i 'dracut'
如果是这种情况，您将看到 2 个具有相同名称的项目。要解决这个问题，您通常会将其删除，但这可能会很困难。你可以尝试这样做：
$ sudo yum reinstall <pkg>
