CentOS 5 yum error: Error: None

On some new installs of CentOS we have been getting the following error while using yum:

[root@s yum]# yum upgrade
Error: None

To fix this phython sqlite and yum must be re-installed.

First remove phython sqlite and yum, then download and re-install them using the following:

rpm -ivh yum-metadata-parser-1.1.2-2.el5.x86_64.rpm
rpm -ivh python-sqlite-1.1.7-1.2.1.x86_64.rpm
rpm -ivh yum-3.2.8-9.el5.centos.1.noarch.rpm
rpm -ivh yum-updatesd-0.9-2.el5.noarch.rpm

Then execute:

yum clean all
yum upgrade

This should fix the issue.

If you are still having issues try the following:

rm /var/lib/rpm/__db*
rpm –rebuilddb
yum clean all
yum upgrade
