我正在运行带有 Apache 的 CentOS 6.4，在通过 WHM 运行 Easy Apache 更新时遇到问题。它因与 yum 相关的错误而失败，因此我决定手动更新 yum。
以下是运行 yum update --skip-broken 时输出的最后一行

Error: 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 nss-softokn-freebl which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of nss-softokn-freebl 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 nss-softokn-freebl.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of nss-softokn-freebl 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 nss-softokn-freebl 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).

我没有按照错误提示的步骤去做，因为我觉得这里有一个更大的潜在问题，有这么多问题。我应该采取什么步骤才能让 yum 完全正常工作？
