As I presented in a previous post the 64bit version of Centos 4.x has some problems with the latest updated kernels that result in up2date failing from functioning with the following error:
up2date -l Fetching Obsoletes list for channel: centos4-Base... Fetching Obsoletes list for channel: centos4-Updates... Fetching Obsoletes list for channel: centos4-extras... Fetching Obsoletes list for channel: centos4-addons... An error has occurred: exceptions.KeyError See /var/log/up2date for more information
Again in logs we can see that it fails to find the proper architecture for the kernel-smp package:
And as in my previous post a quick solution to fix this problem, is to install manually the updated package to fix this problem:
And, up2date will start working again :–).
