Ubuntu remastering problem.

[note]

Hello all,

I try to build my own install cd.I read howto build it form
https://wiki.ubuntu.com/InstallCDCustomizationHowTo and
do step by step.When I install my own cd that has error at
Configure apt step.

This is my step on Ubuntu 5.10:

# sudo -s
# cd /home/jettana
# apt-get source ubuntu-keyring
# cd ubuntu-keyring-2005.01.11/keyring
# gpg --import < ubuntu-archive-keyring.gpg
# gpg --list-keys "Jettana Mutchakwnag"
# gpg --export  FBB75451 437D05B5 MYID > ubuntu-archive-keyring.gpg
# cd ..
# dpkg-buildpackage -rfakeroot -m"Jettana Mutchakwang
<note_jettana at hotmail.com>"
# mkdir /home/old
# mkdir /home/rebuild
# rsync -azvb --delete --backup-dir=/home/old/ /media/cdrom0 /home/rebuild
# cd /home/rebuild
# mkdir -p dists/breezy/extras/binary-i386 pool/extras/
# vi dists/breezy/extras/binary-i386/Release
     Release file :
          Archive: breezy
          Version: 5.10
          Component: extras
          Origin: Ubuntu
          Label: Ubuntu
         Architecture: i386
# cp /home/jettana/ubuntu-keyring*deb /home/rebuild/pool/extras/
# apt-ftparchive packages  /home/rebuild/pool/extras/ >
/home/rebuild/dists/breezy/extras/binary-i386/Packages
# apt-ftparchive -c ../apt.conf release /home/rebuild/dists/breezy >
/home/rebuild/dists/breezy/Release
# gpg --output  /home/rebuild/dists/breezy/Release.gpg -ba
/home/rebuild/dists/breezy/Release
# mkisofs -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot
-boot-load-size 4 -boot-info-table -J -hide-rr-moved -o myInstallCD.iso
-R /home/rebuild

When I burn it and try to install that have error  at step of "Configure
apt".
