I had run yum update in terminal when my laptop shutdown abnormally, causing the update to be interrupted. After rebooting and running the update again, I ran across the multilib version problem.
The fix:
sudo yum clean all
sudo rpm --rebuilddb
sudo yum update --skip-brokenIf that doesn’t work:
package-cleanup --cleandupes
yum distro-syncThis resolved the conflicting 32-bit and 64-bit package versions.
