I am trying to update x86_64 from 5.2 to 5.4 I am trying to update glibc first (before yum -y upgrade) with the command yum update glibc glib-devel glibc-headers gives me the following: package glibc-devel needs glibc-headers = 2.5-24.el5._2.2 this, is not available package glibc-devel needs glibc = 2.5-24.el5._2.2, this is not available. am I missing something? usually this works fine.
