Centos 6.6：[yum install *anything*] 失败，出现

tag-icon • tag-icon centos installation yum 32bit-64bit gcc
Centos 6.6：[yum install *anything*] 失败，出现

我在 Centos 6.6 上安装或升级任何东西时遇到了一些问题。问题基本上在主题名称中总结出来了。当我尝试：

yum install gcc-c++

我得到：

...
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 libgomp which is missing some
        dependency that another package requires. Yum is trying to
        solve this by installing an older version of libgomp 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 libgomp.otherarch ... this should give you an error
        message showing the root cause of the problem.

     2. You have multiple architectures of libgomp 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 libgomp 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: libgomp-4.4.7-3.el6.i686 != libgomp-4.4.7-11.el6.x86_64
Error: Protected multilib versions: libstdc++-4.4.7-3.el6.i686 !=libstdc++-4.4.7-11.el6.x86_64
Error: Protected multilib versions: libgcc-4.4.7-3.el6.i686 != libgcc-4.4.7-11.el6.x86_64
Error: Protected multilib versions: cpp-4.4.7-3.el6.i686 != cpp-4.4.7-11.el6.x86_64

而且这个问题不允许我在系统上进行任何安装。由于我是服务器新手 - 我已经花了大约 3 个小时来解决这个问题 - 到目前为止我发现的任何建议似乎都不起作用。有什么想法可以解决这个问题吗？

更新 1 和 2：

1）

uname -a 
... 2.6.32-504.16.2.el6.x86_64 #1 SMP Wed Apr 22 06:48:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

2）

yum repolist all
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
repo id                 repo name                                 status

答案1

RHN 的建议是降级软件包：

yum downgrade libgomp
yum downgrade libstdc++
yum downgrade libgcc
yum downgrade cpp

答案2

我通常在更新安装了等效 32 位软件包的 64 位软件包时遇到此问题，但 32 位更新软件包不存在，可能是因为未订阅 32 位频道，或者当前频道没有更新的 32 位频道。如果我不需要 32 位版本，我会将其删除，然后尝试更新。
