为什么我的RHEL6 x86_64服务器试图安装libselinux.i686？

Question

刚刚在测试VirtualBox服务器上使用RHEL6DVD进行了新的安装：

[root@bt-rhel6-1 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.1 (Santiago)

我确信这是一台x86_64机器：

[root@bt-rhel6-1 ~]# uname -a
Linux bt-rhel6-1.local 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

也没有安装其他i686包：

[root@bt-rhel6-1 ~]# rpm -qa | grep i686
[root@bt-rhel6-1 ~]# rpm -qa | grep x86_64 | wc -l
331

但当我做yum update时：

[root@bt-rhel6-1 ~]# yum update 2>&1 | grep i686

怎么回事？

Answer 1

这是由于selinux-ruby包错误造成的。

@Mark推荐的yum -v update命令帮助我解决了这个问题。我能够通过手动安装一个较新的软件包来绕过它，一切都很好。
