yum安装报错之版本冲突

34524213

                      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
