Dear Santino,

Thank you for sharing the workaround to avoid the error related to
/usr/lib/grub/grub-multi-install on Ubuntu Noble 24.04. It's great to hear
that renaming the file ubuntu.sources to ubuntu.sources.old in the
directory "/etc/apt/sources.list.d/", followed by logging out and logging
back in, helped you successfully complete the installation.

To address the error you encountered, I recommend checking the debconf
selection variable mentioned in the error logs. It seems that the absence
of this variable might be causing the issue with
/usr/lib/grub/grub-multi-install. You may need to ensure that the necessary
debconf selection variable is set correctly before running the installation
process.

If you encounter any further difficulties or need additional assistance,
please feel free to reach out. I'm here to help you resolve any issues you
may face during the installation process.

Best regards,

Devjyoti Ghosh
