I use Centos 6.4

When I tried to install libgcc with yum install libgcc.i686 I took following massages.

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

 2. You have multiple architectures of libgcc 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 libgcc 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: libgcc-4.4.7-4.el6.i686 != libgcc-4.4.7-3.el6.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles –nodigest

How can I install libgcc.i686 ?

It seems your libgcc.x86_64 has a different version than the libgcc.i686 you are trying to install (4.4.7-3 vs. 4.4.7-4). Try to update the x86_64 lib together with the installation of the i686-lib:

yum install libgcc.x86_64 libgcc.i686

I've hit this after interrupting yum update (during an ansible run in my case). After reading this thread I eventually fixed it with:


package-cleanup --cleandupes


Though before that I'd also tried running commands as @etagenklo suggested, and also tried:


yum-complete-transaction
yum-complete-transaction --cleanup-only
yum check # report generally
package-cleanup --dupes # report on duplicate packages in particular


I think it worth to mention because it was my issues check

/etc/yum.repos.d/*

and check if there is not used or unofficial source

How can we fix this error?

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




2. You have multiple architectures of apr 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 apr installed already.
   You can use yum check to get yum show these errors.
