CentOS 6.2 unable to update using yum!!!

The CentOS 6.2 was unable to update using yum due to failure on system, I did accidentally reboot during the update process.  Then I discovered that yum unable to update with following error:

... Many errors and some concerning glibc

You could try using --skip-broken to work around the problem

It does not help it was claiming that:
glibc is protected_multilib
To fix:

yum clean all

package-cleanup  --cleandupes


yum check-update

yum update --setopt=protected_multilib=false --skip-broken
