I'm using CUBIC to create a custom Ubuntu ISO. I have downloaded ubuntu-16.04.3-server-amd64.iso as a base image, and specified ~/cubicworkspace as my working folder. But when I click "Next" and it is supposed to bring me into the chroot-ed environment, I get:
WARNING! You are NOT in the chroot environment. Exiting.
The host system is a fresh install of Ubuntu 16.04 desktop. I confirmed squashfs-tools are installed. I can't find useful/relevant docs anywhere. Help? :)
I tried following some manual creation steps here to the point where I ran
unsquashfs and mounted a few system directories in the chroot, and then when I moved the "unsquashed FS" into the folder in my CUBIC workspace, I run cubic again, I do get:
You are in the chroot environment.
And I can do some customizations, but then when I click Next, CUBIC says "You have exited from the terminal. Click the Back button to re-enter the chroot terminal." and the Next button is grayed out. :(
How do I fix this so that CUBIC just works? Apparently my little hack doesn't work to the point where I can actually make the image. And the wiki I linked to seems really outdated...
