我在 aws 上运行 RedHat Linux。当我运行 yum update 时，会出现以下问题。我该如何解决这个问题？

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

【解决方案1】：

您说您正在运行 Red Hat，但您的 yum 显示您有 CentOS 存储库。请先检查一下。

如果你安装了 yum-plugin-priorities（你可以检查一下）

[root ~]# yum repolist
Loaded plugins: downloadonly, fastestmirror, keys, list-data, priorities, replace, versionlock
...

你需要添加

priority=1

到 /etc/yum.repos.d/Centos-Base 中的 [base] 和 [updates] 所以它看起来像：

[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=1

#released updates 
[updates]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=1

然后运行（缓存清理可能不是必需的，但为了更好的措施：

yum clean all
yum update

我有这个问题有一段时间了，这就是解决这个问题的方法：

ChrisN 的回答帮助我解决了类似的问题。我没有安装优先级插件，但我缺少 “更新” 部分。我禁用了默认的 CentOS-Base repo 并安装了自定义的。而那个缺少 [updates] 部分。所以我添加了one。在那之后，yum update 修复了这个问题，并且我安装了依赖于该版本 perl 的后续包没有问题。
