==== Protected multilib versions: package-2.x86_64 != package-1.i686 ====

=== Description ===

>You are unable to install or update multilib package. Yum gives the error: Protected multilib versions: package-2.x86_64 != package-1.i686
-Red Hat [[https://access.redhat.com/solutions/2801851|KB 2801851]]

=== Reason === 

>Multilib means support for multiple architectures. This issue arises when .x86_64 and .i686 packages are not the same version. If both the 64 bit and the 32 bit version of a package are available in the repository, they must be the same version. 
-Red Hat [[https://access.redhat.com/solutions/2801851|KB 2801851]]

=== Fix === 

>Verify your yum cache is up to date with the repo

><code># yum clean all</code>

>List out all the packages and check to see if everything is available that you need available
><code># yum list all --showduplicates
# yum list <package> --showduplicates</code>

>Verify there are no excludes or version locks applied to your system
><code>
# grep exclude /etc/yum.conf
# yum versionlock list
# subscription-manager release</code>

>Check for pre-existing problems in the rpm database
><code>
# yum check
# package-cleanup --dupes
# package-cleanup --problems</code>

>Rebuild the database with
><code># rpm --rebuilddb</code>



>Removing the Conflicting Packages\\ If only after you have run the yum clean commands and rebuilt the database and you are still receiving the issue, then the only other option is to remove the package forcefully. But please note: If the package has many core dependencies and its removed, then this could break the server and it would be very difficult to recover from. Therefore this option is not recommended, in this case seek Red Hat support. For non production servers, use this option at your own risk.
