Issue:
The following errors occurred when installing SystemEDGE in RedHat 7.3.
yum install libstdc++.i686

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

    2. You have multiple architectures of libyaml 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 libyaml 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).
Resolution:
It is the Linux yum library problem.
Arrange the libstdc++ dependency setting.
$ sudo yum update libstdc++ --exclude libstdc++.otherarch
