Yum error: No module named sqlite

Today we upgraded one of our centos 4.8 server to centos 5.4 via yum. But after upgrade yum seems to be showing sqlite error.

[root@server1]# yum clean all
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named sqlite

Please install a package which provides this module, or
verify that the module is installed correctly.

It’s possible that the above module doesn’t match the
current version of Python, which is:
2.4.3 (#1, Sep  3 2009, 15:37:12)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]

If you cannot solve this problem yourself, please go to
the yum faq at:

To fix this download the latest python-sqlite rpm from CentOS 5.4 mirror and peform a forceful upgrade.

[root@server1]# rpm -Uvh python-sqlite-1.1.7-1.2.1.i386.rpm –force
