今天早上我试图在我的一台服务器上安装libvirt。 yum安装失败，出现与plymouth-core-libs软件包相关的multilib问题。 后来，在尝试yum更新时，我得到了一个类似的问题，但是multilib问题的包是：dbus-libs。
再仔细观察一下，看起来好像yum尝试安装这些软件包的32位（i686）版本出于某种原因，尽pipe安装了64位软件包。 rpm -qa显示没有安装这些软件包的32位版本。
有什么想尝试下一个尝试进入一个良好的状态（并希望更喜欢64位软件包）？

This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for plymouth-core-libs which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of plymouth-core-libs of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude plymouth-core-libs.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of plymouth-core-libs installed, but yum can only see an upgrade for one of those arcitectures. If you don't want/need both architectures anymore then you can remove the one with the missing update and everything will work. 3. You have duplicate versions of plymouth-core-libs installed already. You can use "yum check" to get yum show these errors. ...you can also use --setopt=protected_multilib=false to remove this checking, however this is almost never the correct thing to do as something else is very likely to go wrong (often causing much more problems). Protected multilib versions: plymouth-core-libs-0.8.3-27.el6.centos.i686 != plymouth-core-libs-0.8.3-27.0.1.el6.x86_64 You could try using --skip-broken to work around the problem ** Found 2 pre-existing rpmdb problem(s), 'yum check' output follows: kernel-2.6.32-431.el6.x86_64 has missing requires of dracut-kernel >= ('0', '002', '18.git413bcf78') kernel-2.6.32-431.3.1.el6.x86_64 has missing requires of dracut-kernel >= ('0', '002', '18.git413bcf78')
首先尝试yum distro-sync 。 如果仍然无法同步，请使用--skip-broken标志。
