Yum update error

edit

When i try to update my fedora 19 using yum ,, i have this problem :

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 lcms2 which is missing some
        dependency that another package requires. Yum is trying to
        solve this by installing an older version of lcms2 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 lcms2.otherarch ... this should give you an error
        message showing the root cause of the problem.

     2. You have multiple architectures of lcms2 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 lcms2 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).
