Red Hat Enterprise Linux 7 - "Protected multilib versions" Errors From yum Trying to Install 32-bit RPMs on a 64-bit OS Installation

Title: Red Hat Enterprise Linux 7 - "Protected multilib versions" Errors From yum Trying to Install 32-bit RPMs on a 64-bit OS Installation
Object Name: mmr_kc-0131971
Document Type: Support Information
Original owner: KCS - Linux
Disclosure level: Public
Version state: final
FACT:RHEL 7.1 (64-bit only OS)
FACT:32-bit libraries required to support 32-bit applications
SYMPTOM:Error: Protected multilib versions: XXXXX != YYYY
CAUSE:RHEL 7 is a 64-bit only OS installation.  However, RHEL 7 still fully
supports the execution of 32-bit applications, and so RHEL 7 provides 32-bit 
RPMs.  When trying to install the 32-bit RPMs, yum fails with a stream of 
"Error: Protected multilib versions" errors:

In general, the error "Protected multilib versions" means that version "X" of 
an RPM is installed for architecture "x86_64", and yum was told to install 
version "Y" of that same RPM for alternate architecture "i686".

To avoid problematic behavior where 32-bit and 64-bit versions of the same 
application behave differently, RHEL prevents installation of different RPM 
versions for different architectures.  While this behavior can be disabled 
by setting:


in /etc/yum/yum.conf, this is generally not recommended.  Instead, it is best 
to install the 32-bit RPM version that matches the 64-bit RPM version currently 

In this case, the issue is slightly different:

  Error: Protected multilib versions: cairo-1.8.8-6.el6_6.i686 !=

While the 32-bit RPM version found by yum (cairo-1.8.8-6.el6_6.i686) is 
indeed different from what is currently installed (cairo-1.1 2.14-6.el7.x86_64),
more importantly the RPMs are from different OS distributions ("el7" versus 
"el6_6").  This means that yum is configured to pull RPMs from a RHEL 6 repo on 
this RHEL 7 system, which is not a valid configuration.
FIX:The solution is to:

1. Remove all RHEL 6 repos from this RHEL 7 server.

2. Using the normal RHEL 7 repo, install the 32-bit RPMs that match
   the 64-bit RPM version currently installed.

The availability and installation of 32-bit RPMs on RHEL7 is illustrated here:

# yum repolist
repo id                     repo name
rhel-7-server-rpms/x86_64   Red Hat Enterprise Linux 7 Server RPMs

# yum search gtk2 --showduplicates | grep -v x86_64
gtk2-2.24.22-5.el7.i686 : The GIMP ToolKit (GTK+), a library for creating GUIs
gtk2-2.24.22-5.el7_0.1.i686 : The GIMP ToolKit (GTK+), a library for creating
gtk2-2.24.28-8.el7.i686 : The GIMP ToolKit (GTK+), a library for creating GUIs

Show the currently installed 64-bit RPM version:

# rpm -q gtk2

The 32-bit versions needed are installed by appending the needed architecture
("i686") to the same package version ("gtk2-2.24.22-5.el7_0.1").  So the command:

# yum install gtk2-2.24.22-5.el7_0.1.i686

will install the matching 32-bit version of the gtk2 RPM along with any
