So, what do I do with the output of yum check?

Question

When I run yum check (or try to use yum to update my system generally), I get the following:

# yum check
Loaded plugins: langpacks, presto, priorities, refresh-packagekit
krb5-devel-1.10.2-12.fc17.x86_64 has missing requires of keyutils-libs-devel

Error: check all

With the duplicates in particular, if I try to uninstall them, a bunch of other packages will be uninstalled (for each package on either side of the "is a duplicate with"). How do I resolve that?

As to the missing requires, I assume I can install the missing requires.

Update: I was able to resolve some of these errors:

1. The sqlite duplicate was resolved by # yum reinstall sqlite-3.7.11-3.fc17.x86_64
2. The missing requires were resolved just by installing them with yum.

3. Attempting to solve the openssl issues with reinstall did not work:

   # yum reinstall openssl

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