Thank you for your reply! It was very helpful to me.
I have figured out why the errors occurred. I changed to SELINUX=permissive
in the /etc/sysconfig/selinux about 2 months ago. Today I have found several
files in /bin, /sbin, /usr/bin, /usr/sbin do not have context when I see the
directory list by 'ls -lZ' command.
I cannot understand why they have blank context. Anyway I have restored
context information by restorecon command. And I could finish successfully
'yum update'.
