Building Ubuntu Local Repository (CD)

I've just read from this site about creating Ubuntu DVD Repositories. I thought I need to create such local repo, but in CDs, as I don't have DVD burner.

First, I created local copy from main repository using debmirror.
In this case, I am using mirror from CBN.

$ debmirror --nosource -m --passive --host=ubuntu.cbn.net.id --root=Ubuntu/ --method=http--progress --dist=breezy --section=main --arch=i386 ubuntu/ --ignore-release-gpg


Creating destination folders for partitioning

$ mkdir ubuntu-cd


Then I partitioned those files using debpartial

$ debpartial --nosource --dirprefix=ubuntu --section=main --dist=breezy --size=CD74 ubuntu/ ubuntu-cd/


After the packages lists had been generated, I created the symlink to the corresponding packages using debcopy script. It can be downloaded from here.

$ ruby debcopy -l ubuntu/ ubuntu-cd/ubuntu0
$ ruby debcopy -l ubuntu/ ubuntu-cd/ubuntu1
$ ruby debcopy -l ubuntu/ ubuntu-cd/ubuntu2
$ ruby debcopy -l ubuntu/ ubuntu-cd/ubuntu3
$ ruby debcopy -l ubuntu/ ubuntu-cd/ubuntu4


The partitioned folders then converted into iso image files, and burnt.

$ mkisofs -f -J -r -o ubuntu-cd-main-0.iso ubuntu-cd/ubuntu0
$ mkisofs -f -J -r -o ubuntu-cd-main-1.iso ubuntu-cd/ubuntu1
$ mkisofs -f -J -r -o ubuntu-cd-main-2.iso ubuntu-cd/ubuntu2
$ mkisofs -f -J -r -o ubuntu-cd-main-3.iso ubuntu-cd/ubuntu3
$ mkisofs -f -J -r -o ubuntu-cd-main-4.iso ubuntu-cd/ubuntu4

$ sudo cdrecord -v dev=/dev/cdrw speed=32 driveropts=burnfree -dao -eject ubuntu-cd-main-0.iso
$ sudo cdrecord -v dev=/dev/cdrw speed=32 driveropts=burnfree -dao -eject ubuntu-cd-main-1.iso
$ sudo cdrecord -v dev=/dev/cdrw speed=32 driveropts=burnfree -dao -eject ubuntu-cd-main-2.iso
$ sudo cdrecord -v dev=/dev/cdrw speed=32 driveropts=burnfree -dao -eject ubuntu-cd-main-3.iso
$ sudo cdrecord -v dev=/dev/cdrw speed=32 driveropts=burnfree -dao -eject ubuntu-cd-main-4.iso

The method to create repo-cd for universe & multiverse repository is similar.
I Just changed the apropriate parameter in debmirror & debpartial.
Now I have access to ubuntu repository even when I am not connected to the net. Right now, I am currently trying to create repo from breezy-updates & security. Hopefully, I will have it mirrored before it changes (again) :-)

i dont quite understand.
Is it mean that u had to download them all first, then burn it, or you download and burn them at the same time.

They are batch processes.
Therefore those steps are sequential
Download-->Split-->Convert-->Burn
Unfortunately, due to limited hd-size, I only made main cd repo only :(
