Kickstart Failing ... Installation Tree not working

[tyronefrance]

Hi guys.. i have created my ks.cfg and placed it in the main directory of the centos6 DVD...

PLEASE can someone help me, this has been bugging me for too long now!

I have updated the isolinux.cfg in the isolinux folder and when i bootup i select the kickstart install and all goes fine...then the partitions are created and after that i am getting the following error:

Unable to read the package metadata. This may be due to a missing repodata directory. Please ensure the the install tree has been correctly generated...
Could not retrieve /mnt/sysimage/var/cache/yum/anaconda-centos-201106051823.i386/2b014e1fcde80ec1cc69d6a048f660f712b1ae2d83d1fc04d3b3c00ade817ec9-primary.sqlite.bz2 matching remote checksum from anaconda-centos-201106051923.i386


I have also attached my kickstart file below is :

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

Sounds like you have modified the DVD, rather than just using the standard DVD image with your kickstart. Just a guess, but perhaps the changes to the DVD are the source of the checksum error.
