--> Finished Dependency Resolution
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 elfutils-libelf which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of elfutils-libelf 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 elfutils-libelf.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of elfutils-libelf 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 elfutils-libelf 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: elfutils-libelf-0.160-1.fc20.i686 != elfutils-libelf-0.157-1.fc20.x86_64
Error: Protected multilib versions: llvm-libs-3.4-6.fc20.i686 != llvm-libs-3.3-0.10.rc3.fc20.x86_64
我想知道其他哪些软件包使用 elfutils-libelf-0.160-1.fc20.i686 如果它们不重要，我将删除它们，希望这可以解决这个问题。如果我有其他方法来解决此问题，请告诉我，我愿意接受建议。
我试过这个
> sudo yum erase elfutils-libelf-0.160-1.fc20.i686

答案1
您安装了 x86_64 和 x86（64 和 32 位）版本，并且由于某种原因可用版本不匹配（需要不同版本的东西）。
您可以尝试使用以下命令删除 i686 版本：
yum erase elfutils-libelf.i686 llvm-libs.i686
这将询问您是否要删除这些（以及依赖于它们的包）。
无论如何，Fedora 20 已经结束生命，请升级。
答案2
您可以运行yum erase elfutils-libelf到需要删除的依赖包以删除 elfutils-libelf。
