Why Cubic doesn't build custom Ubuntu 19.04 ISO without installing the Ubuntu distro?

Asked by Robert Zaku on 2019-04-22

Hello!
I just downloaded Ubuntu 19.04 desktop. I didn't install it on my computer, I chose Try Ubuntu on boot.
After this I installed Cubic, installed other programs, games and some packages, tweaked GNOME themes, changed the desktop background and then I began using Cubic to build custom Ubuntu ISO, but it didn't finish it successfully.
It's stuck at 94%.
I tested it sometimes, it's always stuck at 94%.
What to do? Thanks!

You ran out of disk space.

You need somewhere to save all those file to, and memory may just no t be enough...

1. You need space for the original ISO
2. You need space for the extracted ISO
3. You need space for the customization/packages you add
4. You need space for the new remastered ISO

You could try to create a Persistent Live ISO on a USB stick that has extra space.
Then you can boot into the Persistent Live ISO, install Cubic, download your ISO, create a project in Cubic and try to customize it. The process may be slow (depending on your USB write times), but it may work.

How much Persistent space do you need?...
1. You need space for the original ISO
    ~ 2GB
2. You need space for the extracted ISO
   ~ 6 GB
3. You need space for the customization/packages you add
  ~ 4 GB
4. You need space for the new remastered ISO
  ~ 4 GB

Allowing space for the Live system, you should have a USB stick of roughly 20 GB (min), and allocate 16 GB (min) for the Persistent storage.

If you use a 32 GB USB stick, allocate 75%-80% for Persistence.

Take a look at MKUSB...

. . .

The alternative is to have at least 20 GB of System Memory, but I've never tried that, so I can't say for sure it would work.

Also, you can boot into a Live Ubuntu ISO, install MKUSB in the Live environment, and then use it to create a Persistent Live ISO on *another* empty USB stick (preferably 32 GB with 75% for Persistence).

Then, boot into the new Persistent Live ISO, and you should have enough space to install Cubic and customize Ubuntu.

Can you help with this problem?
