Problems upgrading from CentOS 5.2 to 5.3

CentOS 5.3 has recently been released and the update appears to automatically upgrades my machine to 5.2 to 5.3. the problem is that the update ends with the following error:

kernel - 2.6.18-128.1.6.el5.i686: failure: RPMS/
kernel-2.6.18-128.1.6.el5.i686.rpm from updates: [Errno 256]
No more mirrors to try.

This error usualy indicate that there is a problem with the yum cache. I took a look at the release notes and it indicated that we may need to update glibc first. Here’s what I did.

1. In CentOS, start a terminal window.
2. su to root.
3. Run the following commands:

   yum clean all
   yum update glibc
   yum update

The first command clears the cache and all of the stale packages. I am not sure why you need to install glibc first, but it’s in the release notes.
