1. You have an upgrade for %(name)s which is missing some

solve this by installing an older version of %(name)s 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 %(name)s.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of %(name)s 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 %(name)s 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
