Question

I would want "program.deb" to be pre-installed to a Ubuntu Live CD.

The comments above link to lots of options. If you choose to use Cubic, here are some detailed steps:

1. Install the software:

   sudo apt-add-repository ppa:cubic-wizard/release
   sudo apt update
   sudo apt install --no-install-recommends cubic
   

2. Create a new project:

   Launch Cubic.

   On the first page, select a new empty directory. (For example, /home/tank/my_live_cd).

   Click Next

   On the Project page, select your original ISO. (For example ubuntu-21.04-desktop-amd64.iso).

   Default values will be automatically filled out, so just click Next.

   

3. When you get to the Terminal page, copy your deb file:

   mkdir Temp
   cd Temp
   

   Drag program.deb onto Cubic's Terminal area to copy it into your new Temp directory.

   

4. Then, install your package from your program.deb file:

   apt-add-repository universe
   apt-add-repository multiverse
   apt install --no-install-recommends gdebi-core
   gdebi program.deb
   

   

   Remove unnecessary files.

   apt autoremove --purge gdebi-core
   cd ~
   rm -rf Temp
   

5. Click through the next pages, accepting the defaults:

   On the Terminal page, click Next.

   On the Packages page, click Next.

   On the Options page, click Next.

   On the Compression page, click Generate.

   On the Generate page, click Finish.

   Click the Close button to exit the application.

Finally, Create a bootable USB, CD, or DVD using your new Live ISO file.
