错误： 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 libXrender which is missing some

           dependency that another package requires. Yum is trying to

           solve this by installing an older version of libXrender 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 libXrender.otherarch ... this should give you an error

           message showing the root cause of the problem.

      

        2. You have multiple architectures of libXrender 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 libXrender 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: libXrender-0.9.8-2.1.el6.i686 != libXrender-0.9.7-2.el6.x86_64
