Can't build Spirallinux iso

[ccmdr]

Hello everyone,
i'm trying to build a spiral linux live iso (GNOME edition) as shown in this thread:
https://github.com/orgs/SpiralLinux/discussions/228#discussioncomment-4809266
So i've created a Debian 11 VM build environment, installed all build dependencies and started the build process with sudo su and ./spiral -i.

But unfortunately the build process stops with an error, apparently a configuration error with the latest kernel: Package linux-image-6.12.22+bpo-amd64. I've attached the entire log file: build-log.txt
I also tried Debian 12 as build environment, but it seems to fail with the same error: build-log-debian12.txt

Why i am doing this? For years i've been using Debian with btrfs/snapshots and switching to Spirallinux would make things a lot easier, since for now i am working with a debian preseed file and some complicated late-commands to set up the btrfs snapshot function automatically on every installation.
So this project is just awesome and looks very promising! Because it handles stuff much more elegant, my preseed solution is basically a hack into the freshly installed sytem, in order to set btrfs subvols for example.
I've installed Spirallinux on a test device and am thrilled so far. I'd still need to set up some things in addition to the spirallinux defaults, to work as my daily driver. And therefore i would have to build a custom spiral iso, being able to roll out the installation including all customizations, just like I currently do with my preseed debian iso. But i haven't added any additional stuff yet, just downloaded the original Spirallinux-GNOME build archive and tried to run the building process.

So it is possible to remove the backports kernel in config/includes.chroot/etc/apt/preferences.d/99backports. in this case the iso is created with kernel 6.1 only and the build works smoothly under debian 12: build-log-stable-kernel-deb12.txt However, since i'd like to keep the support for virtualbox, i didn't go any further at this point.
(Building the iso with only 6.1 kernel on Debian 11 wouldn't work either: build-log-stable-kernel-deb11.txt )

Anyone have any ideas what to try next?

I think you have to comment out or delete the following lines in the file SpiralLinux-Gnome/config/package-lists/spirallinux-Gnome-packages.list.chroot:

broadcom-sta-common
broadcom-sta-dkms

The newer backport kernels have a problem with these two packages, so you have to remove them. The problem also occurs if you want to update from an older backport kernel to a new one (e.g. from 6.11.x to 6.12.x).

The problem was discussed here, for example:
https://github.com/orgs/SpiralLinux/discussions/529

Edit:

Out of interest, I ran a build process without the two packages under Debian 12 and it went through without any problems.

Oh yes that's it! Thank you so much!
Now i understand, i had to remove kernel 6.12 on my test device, because after an update the laptop didn't boot anymore. I thought it was a bug with the kernel, but now after removing the broadcom drivers i was able to reinstall the kernel and the boot works!
And also building the iso on debian 12 works now perfectly, thanks!

EDIT: just because i'm curious, as written in this post
https://github.com/orgs/SpiralLinux/discussions/321#discussioncomment-7235501,
debian 11 should be used as build environment, because bugs in the debian 12 version of live-build prevent building on debian 12. so the bug seems to be fixed?

I haven't had any problems building on a Debian 12 system so far, so I can't comment or contribute. (Apart from this attempt, which was not the fault of live-build, but of me.)

Perhaps @geckolinux as the maintainer can say more about this?
