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@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@mailgw yum.repos.d]# yum upgrade Loading "protectbase" plugin Setting up Upgrade 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@mailgw yum.repos.d]# yum update kernel-smp 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 Could not find update match for kernel-smp No Packages marked for Update/Obsoletion

My all boxes still have below kernel.

[root@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@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. # #
