Hi,

My all boxes are running CentOS 4.4. When They were running CentOS 4.3. it
upgraded to CentOS 4.4 due to yum.

But, This time, My all boxes are still running CentOS 4.4.

I did below commands, But no luck yet.

[root at mailgw yum.repos.d]# yum update
Loading "protectbase" plugin
Setting up Update Process
Setting up repositories
Reading repository metadata in from local files
Excluding Packages from Red Hat Enterprise Linux 4 - i386 - ATrpms
Finished
218 packages excluded due to repository protections
No Packages marked for Update/Obsoletion

[root at mailgw yum.repos.d]# yum upgrade

[root at mailgw yum.repos.d]# yum update kernel-smp
Loading "protectbase" plugin

My all boxes still have below kernel.

[root at mailgw yum.repos.d]# uname -r
2.6.9-42.0.10.ELsmp

So I want to know how to upgrade to centOS 5 by using yum.

Pls note that I do not need a fresh install.


here are my .repo files.

[root at mailgw ~]# cat /etc/yum.repos.d/CentOS-Base.repo
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for
CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS
updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
