You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
答案1
CentOS 6 附带 Python 2.6.6，但您显然已经安装了 Python 2.4 或使用其 CentOS 通过 RPMForge 针对 Python 2.4 构建的软件包5el5RPM，如某些给出的文件名中的 所示。
您需要删除这些软件包并安装正确的 EL6 版本。
一般来说，在 Red Hat 类型的 Linux 上混合使用两个不同版本的 Python 是一个非常糟糕的主意，因为大部分核心操作系统都是基于 Python 的。你肯定会遇到这样的冲突。
有一些安全的方法可以设置第二个版本的 Python 的独立安装，但这是一个单独的问题。
答案2
如果盲目遵循跳过破损包裹的建议，问题将会更加严重。问题来自混合存储库。要开始修复问题，请禁用 rpmforge 存储库，如果更新仍然失败，请尝试更新部分列表以减少冲突包的数量。
即使出现冲突，yum update 仍然接受可选的包名称，例如，
yum update chkconfig.x86_64
正如@warren-young 所说，结束修复系统时，必须删除与CentOS冲突的软件包。如果yum update.
