CentOS：Yum 依赖问题

我正在尝试在 CentOS 上安装 fail2ban，但我不明白为什么它无法安装：

[root@server ~]# yum install fail2ban

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
[root@server ~]#

这可能是由于 CentOS 6 上来自过时（例如 el5）仓库的仓库和/或软件包之间存在冲突。请查看此主题获得关于从哪里开始进行故障排除的良好提示。

这对我有用，YMMV：

  1. 查找所有随 el5 安装的软件包并将其删除。你可以像这样找到它们：

    rpm -qa|grep el5

  2. 删除 el5 存储库

    yum repolist
rpm -e <repo name>

  3. 安装正确的 EPEL 仓库。如果你和我一样使用的是 CentOS 6 32 位：

    rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

  4. 清理缓存yum（首先尝试一下 - 也许这就是全部）：

    yum clean

    或者

    yum clean expire-cache
