如何解决 yum update 上的 multilib 问题？

Question

当我尝试在 centos 7 上更新 yum 时，出现 multilib 错误：

Errore:  Multilib version problems found. 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 libnghttp2 which is missing some
         dependency that another package requires. Yum is trying to
         solve this by installing an older version of libnghttp2 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 libnghttp2.otherarch ... this should give you an error
         message showing the root cause of the problem.
    
      2. You have multiple architectures of libnghttp2 installed, but
         yum can only see an upgrade for one of those architectures.
         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 libnghttp2 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).
    
    Versioni multilib protette: libnghttp2-1.33.0-1.1.el7.x86_64 != libnghttp2-1.31.1-2.el7.i686

我试图通过以下方式解决问题：

sudo yum erase libselinux.i686

但这并没有改变。

sudo package-cleanup --dupes

什么都不给。 如果我执行：

sudo yum list --showduplicates libselinux
Plugin abilitati:fastestmirror, langpacks

我应该怎么做才能解决它？

谢谢，

Answer 1

这个问题显然是通过执行来解决的：

 sudo yum erase libnghttp2.i686

在那之后 yum 更新无缝运行。
