Yum Update 在 Perl 软件包方面存在问题

Question

我在 aws 上运行 RedHat Linux。当我运行 yum 更新时，它以以下问题结束。我该如何解决此问题？

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

你说你正在运行红帽，但你的 yum 显示你有 CentOS 存储库。请先检查一下。

如果您安装了 yum 插件优先级（您可以检查这一点）

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

您需要添加

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，但为了很好的措施：

yum clean all
yum update

我有一段时间了这个问题，这就是解决方案：

Answer 2

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。我已经禁用了默认的 CentOS-Base 存储库并安装了自定义存储库。那个缺少[更新]部分。所以我加了一个。之后， yum update解决了这个问题，并且在安装依赖于该版本的perl的后续软件包时，我没有遇到任何问题。
