# yum update....---> Package libcap-ng.i686 0:0.7.5-4.el7 will be installed---> Package libstdc++.i686 0:4.8.5-16.el7 will be installed--> Finished Dependency ResolutionError: 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 glibc which is missing some  dependency that another package requires. Yum is trying to  solve this by installing an older version of glibc 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 glibc.otherarch ... this should give you an error  message showing the root cause of the problem.  2. You have multiple architectures of glibc installed, but  yum can only see an upgrade for one of those architectures.  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 glibc 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).
