我在Centos 6.6上安装或升级任何问题。 问题在主题名称中被概括得很多。 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
而这个问题不允许我在系统上进行任何安装。 因为我是一个服务器新手 – 我已经花了大约3个小时来处理这个问题 – 没有任何build议，我发现迄今似乎工作。 任何想法如何解决它？
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）

RHN的build议是降级软件包：
yum downgrade libgomp yum downgrade libstdc++ yum downgrade libgcc yum downgrade cpp

我通常会在更新安装了等效的32位软件包的64位软件包时得到此信息，但32位更新软件包不存在，可能是因为32位通道未订阅，或者当前通道没有更新的32位通道。 如果我不需要32位版本，我将其删除，然后尝试更新。
