Do you try to build a installer image, or a live image?

I can reproduce after building a netinstall image

Sorry I did not explain myself correctly.
We create a live image. It is when we start installation to disk, with the option highlighted in the image below, that the error appears.
We do it that way because de --installer option at build does not allow us for a fully automated install with all modifications we need.
I've just tested again with the standard configuration without any modifications, and I can reproduce the behavior in my local Kali

Thanks!

I am also facing the same issue for a few days now using a custom implementation of the live build that is automated.
This happens regardless of BIOS or UEFI, bare metal or VM.

I had the same issue but fixed it by not using the netinstall image. If you got persistence on your USB, you can update via apt just fine.

I uploaded an updated version of the debian-installer, and it fixes the issue. The weekly image 2024-W02 is fixed, as far as I can see. Please try to rebuild your custom image, and it should be fixed for you as well.

Please confirm so I can close this issue. Again: thanks for reporting it!

Thanks @arnaudr, this is looking good for me!

Updated our mirror, rebuilt from scratch and everything is working perfectly now.
Thank you very much!

Your work and effort are really appreciated

Thanks for the feedback, glad to hear that the issue is resolved! And thx for the kind words!
