Steve McIntyre has posted an update on Debian’s UEFI Secure Boot status, to the debian-boot and debian-efi mailing lists. Excerpt:
I’ve just pushed changes to a few bits of d-i this weekend to make SB work for amd64:
* build/util/efi-image: […]
* build/config/arm.cfg, build/config/x86.cfg: […]
* debian/control: […]
* grub-installer/grub-installer: […]
The effect of these changes is that the next daily and weekly debian installer images (tomorrow) should Just Work (TM) end-to-end with UEFI Secure Boot. The changes to efi-image also mean that our next live image builds will do SB (for live and installation).
I’ll test all these again in the next couple of days to verify that things have pulled through as I expect, then it’s time to post to d-d-a and write a blog too. We’ve made great progress already. These last changes just tie it all together for end users.
