I'm trying to make a custom Ubuntu Server iso file. Kickstart file (ks.cfg) runs smooth when there is no %post in the file and Ubuntu installs correctly with ks configuration.

Installation finishes installing base, apt, grub and It echos: Kickseed Running... and it freezes @ 0%

Installation goes well if I only add apt-get update (or something like mkdir) in %post section, but apt-get upgrade, apt-get install apache2 doesn't work

I have created dozen iso images and installed them in Virtual Box.I have been googling for 3 days and checked out ubuntu forums but haven't figured out the issue. I appreciate your help.

This is how I made the iso image. My ks.file and txt.cfg files located in isolinux directory:

root@ubuntu:/home/work

mount -o loop ubuntu-12.04-amd64.iso original-iso/

rsync -a original-iso/ custom-iso/

cp ks.cfg custom-iso/isolinux/

cp txt.cfg custom-iso/isolinux/

chmod -R 777 custom-iso/

#Creating Iso image

mkisofs -D -r -V “$IMAGE_NAME” -cache-inodes -J -l -b 

isolinux/isolinux.bin

-c isolinux/boot.cat -no-emul-boot -boot-load-size 4

-boot-info-table

-o ~/ubuntu-12.04-alternate-custom-amd64.iso custom-iso/

ks.cfg

TRY This. It should work
