Live CD Ubuntu Customization Kit (UCK) without Internet

Hi friends,

As many of you know that, UCK (Ubuntu Customization Kit) requires Internet when customizing the Live CD.

Why we need Internet while customization?

• To get the updates from the repositories we need the internet.
• To install any software using apt-get/synaptic package manager.

Do we need Internet all the time?

According to me, We may not need the Internet for small updates.

So, I have modified the customization scripts to work without Internet.

Pre-requisites:

Please download the following files.

sources.gz: 

According the ubuntu distro, we need to get the sources.gz from the link

http://archive.ubuntu.com/ubuntu/ubuntu/ubuntu/dists/$DISTRO_CODENAME/main/source/Sources.gz

gfxboot-theme-ubuntu_x.x.x:

http://archive.ubuntu.com/ubuntu/ubuntu/ubuntu/pool/main/g/gfxboot-theme-ubuntu/

Please place these two files in ~/Softwares/UCK/ directory

Note: ~ is home directory of the user.

Apply Patches

If you installed UCK, you will having the /usr/lib/uck/customization-profiles/localized_cd/ directory

In that directory, you will be having customize and customize_iso scripts.

Those two scripts will be copies to /home//tmp folder while running the UCK.

So, please apply the following patches in /usr/lib/uck/customization-profiles/localized_cd/ 

Now apply the patch as shown below

$ patch -u customize customize.patch

$ patch -u customize_iso customize_iso.patch

Ubuntu Customization Kit (UCK) Problem Solved in 12.04 Precise Pangolin

Hi friends,

I had an issue with UCK (Ubuntu Customization Kit) in Ubuntu 12.04.

Problem:
After selecting the language pack, the UCK crashes. It doesn't show the error also.

Solution:

• I have uninstalled it completely.
• I have delete the folder /usr/lib/uck --Doesn't know this is right cause
• I have updated my Ubuntu 12.04 with latest updates --For no reason, Just tried my luck
• Then I have tried to do as mentioned in the link.
• This problem was resolved but a new problem came into picture i.e. resolve.conf problem
• After googling, I found this patch which helped me to resolve the problem.

Now I am happy that, I am able to customize my latest Ubuntu 12.04 Precise Pangolin also.
