DIDN'T CREATE ISO FILE

[DemaxDragonTix12]

So I want to create my own ubuntu distro, it succesfully created without any errors and it says it created the iso file but it doesn't show

"Drive current: -outdev 'stdio:/media/username/bf00bd81-d195-4385-bff9-ffcaa06cf25c/live-cd.iso'
Media current: stdio file, overwriteable
Media status : is blank
Media summary: 0 sessions, 0 data blocks, 0 data, 348g free
Added to ISO image: directory '/'='/tmp/grub.v9zHw8'
xorriso : UPDATE : 574 files added in 1 seconds
xorriso : FAILURE : File exceeds size limit of 4294967295 bytes: '/media/username/bf00bd81-d195-4385-bff9-ffcaa06cf25c/CD/casper/filesystem.squashfs'

Added to ISO image: directory '/'='/media/username/bf00bd81-d195-4385-bff9-ffcaa06cf25c/CD'
xorriso : UPDATE : 586 files added in 1 seconds

grub-mkrescue: error: xorriso invocation failed"

I looked and no live-cd.iso, I put to another directory instead of home/distroshare, I even tried putting to home/distroshare, same thing, any ideas?? I can't find live-cd.iso, is it hidden file or it didn't create?? Anyone have this same issue?

I use Ubuntu 20.04 LTS

I don't have a iso with the error:
grub-mkrescue: error : mformat invocation failed
note both errors are grub-mkrescue.

Hey @Pandademic
You just need too install the package mtools.
