更新openssh-server的yum错误

Question

我试图在Centos 7.4服务器上运行该命令：

yum update openessh-server

但是，我收到以下错误：

我的直觉是清除缓存并重建rpm db，执行包清理，删除openssh-server，然后安装openssh-server。我还没有这样做的原因是因为我害怕破解SSH，这就是我访问服务器的方式。我想知道是否有人可以提供一些建议，因为我在yum / rpm错误方面不是很有经验。我也很乐意在需要时提供更多信息来更新问题，因为我不确定要包括哪些内容。

Answer 1

所以对我有用的解决方案是：

yum clean all
yum remove openssh-server
yum install openssh-server

我从控制台这样做是为了保存，但事实证明它通过SSH可以正常工作。
