Cubic hangs on creating customized disk image from ubuntu 18.04 ISO

Asked by Alex Vim

Hello, I'm experimenting with Cubic using ubuntu 18.04 host system and trying to modify standard ubuntu 18.04 ISO.

On the last step cubic hangs when executing "Generate the customized disk image step". No error message is present.
Any clues what's wrong? Any log file to look at?

Thanks.

This should be working without issue.

Would you please run Cubic from the command line?
(Just open a terminal window, type "cubic", and press <Enter>).

(To save time, you don't have to do your full customization inside the chroot environment).

After you experience the "hang" cut and paste the log output here.

Its looks to be FileNotFound error for the output file. It is true that output file doesn't exist yet, because it is the first time I tried to create it.

Here is list of my working folder if needed:
~/disk1$ ls -ao

Alex,

The file "ubuntu-desktop-amd64.iso" should exist by the time you are seeing the FileNotFound error.

I could not recreate this issue on my end, so we will need to do a little more debugging on your machine.

It is likely the the command just before this error does not succeed.
See item [3] below to find out what the error could be.

---[1]---

Please let me know what is the output of:

    $ sudo dpkg-query --showformat="\${Version}\n" --show cubic

---[2]---

Is "/home/test/disk1" a remote or mounted file system?

Is "/home/test/Downloads" a remote or mounted file system?

---[3]---

Please launch cubic from the command line, as before.
(Work with your existing project in "/home/test/disk1/", if it is still available).
Navigate through the Cubic pages by clicking Next, until you get to the page where you can select the ISO Kernel.

At this point, do *not* click Next, and do *not* close or exit Cubic.
Then, open a new terminal window on your ~host~ machine.

Inside the new terminal window, execute the following:

$ sudo xorriso -as mkisofs -r -V "Ubuntu 18.04 LTS amd64" -cache-inodes -J -l -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -c isolinux/boot.cat -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat -o "/home/test/disk1/ubuntu-desktop-amd64.iso" .

(Be sure to copy the space followed a "." at the end of the above command, when you cut-and paste).

Please share the output of this command. (There may be an error).

Alex,

If you get a chance, would you execute the following, and let me know the results?

(Basically, it's the same command as step 3 above, but I want you to cd into the ~/test/custom-live-iso directory, first).

$ cd /home/test/custom-live-iso

$ sudo xorriso -as mkisofs -r -V "Ubuntu 18.04 LTS amd64" -cache-inodes -J -l -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -c isolinux/boot.cat -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat -o "/home/test/disk1/ubuntu-desktop-amd64.iso" .

Well, this is totally my fault - I'm using VBOX and assigned to little disk space to it.

xorriso fails with no disk space available.

Thanks for your time.
