Hello,
I'm trying to get used to run_qemu script in order to later manage multiple vm.
Following instructions from the readme, run_qemu.sh fails at some points:

debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 78.)
debconf: falling back to frontend: Readline
update-initramfs: deferring update (trigger activated)

‣ Error: Workspace command kernel-install add 6.9.9 /boot/vmlinuz-6.9.9 returned non-zero exit code 1.

I've compiled a 6.9.9 linux kernel, with by default option, (make menuconfig && make)
The only lines I've modified are distro=debian and rev=bookworm at the beginning of the script.
run_qemu.sh is not run as root

Versions:
I was using mkosi 14, and switch to latest stable release: 23
dracut :102-3
qemu : 9.0.1
I'm under Debian 12

@SeiDPierre I don't run Debian, so don't have insights on what might be going on.

@miguelinux since you did some work recently with Debian support, do you have any ideas?

When using mkosi v14-, a recent Arch Linux also fails exactly like this for me.

But support for mkosi v15+ is coming, please help test #80 EDIT: merged, but now we have incremental build issue #88
