Currently, I am trying to build Ubuntu 24.04 with xorriso, but failed with following error output.

The Ubuntu I used is a daily build version: https://cdimage.ubuntu.com/daily-live/current/noble-desktop-amd64.iso

and I have updated the xorriso to the latest version:xorriso-1.5.6-5.el7.x86_64

I am not familiar with xorriso, so, if anyone who can help me with this, I would appreciate it.

Edit:

The problem is the option -grub2-boot-info which should be given before option -eltorito-alt-boot switches the argument scope to the second boot image. Your xorriso run applies it to the appended partition with the EFI boot image.

Try:

... -b boot/grub/i386-pc/eltorito.img -c boot.catalog -no-emul-boot -boot-load-size 4 -boot-info-table --grub2-boot-info -eltorito-alt-boot -e '--interval:appended_partition_2:::' -no-emul-boot ...

My now outdated answer before i discovered the xorriso arguments in your post:

Without knowing the xorriso arguments and seeing the other messages of xorriso, i can only state that this error happens if a boot info table shall be patched into an El Torito BIOS boot image that is not a file in the ISO 9660 filesystem but rather an appended partition.

In noble-desktop-amd64.iso the BIOS boot image is a file named /boot/grub/i386-pc/eltorito.img whereas the EFI boot image is an appended partition which needs no patching with a boot info table. So it is not clear why your xorriso run was instructed to patch a partition.

A test with xorriso's proposals for repacking yielded no error:

xorriso-1.5.6 -indev noble-desktop-amd64.iso -outdev test.iso -boot_image any replay -changes_pending yes
