Description Matthew Yates 2012-05-10 20:57:07 UTC

Description of problem:

When trying to install the package libxcb-devel-1.8-2.fc17.x86_64, an i868 version of the package libxcd is called as a dependency. Which causes:
Error: Protected multilib versions: libxcb-1.8-2.fc17.i686 != libxcb-1.8.1-1.fc17.x86_64
which prevents installing the X11 devel packages. 

Version-Release number of selected component (if applicable):

How reproducible:

Every time on Fedora 17 beta

Steps to Reproduce:

yum install libxcb-devel-1.8-2.fc17.x86_64
  
Actual results:

Comment 1 James Antill 2012-05-11 17:10:56 UTC

 The problem is that the isntalled version "libxcb-1.8.1-1.fc17" is newer than the available version "libxcb-1.8-2.fc17" (1.8.1 > 1.8). Yum won't do automatic downgrades, so it tries to solve the problem by installing the .i686 version ... but that hits multilib conflicts.

 Use downgrade/distro-sync, and all should be fixed.
