Package: grub-efi-amd64
Summary: The defect occurs on a bullseye.rc1 install ;
install went normally using bullseye rc1; booting the installed
system fails
the UEFI boot sequence on a system that doesn't support secure boot
fails trying to access owner MOK
Hello Debian bullseye boot sequence team,
I dont have a screen grab and the message only stayed up a few seconds.
The system is a Dell Precision T1200 E3, 16GB of memory, SSD, installing
off CDROM to an encrypted LVM with dedicated /boot and encrypted LVM
partitions.
The bullseye system was installed using the bullseye rc1 system for an
amd64 target.
Installation went normally; the difficulty lies when attempting to boot
the installed system off the ssd.
Again, the boot time error message that briefly showed on the screen is
that the MOK machine owner key could not be accessed.
I found a workaround using a previously installed Buster 10.9 system
with a similar configuration:
a) boot Buster 10.9 dvd in recovery mode
b) rewrite the SSD bootstrap so the Buster 10.9 system boots
c) reboot into Buster 10.9
to diagnose what was going on I ran : mokutil --disable-validation
the error message returned was 'this system does not support
secure boot'
d) update buster /etc/grub.d/40_custom so it has the bullseye rc1
boot stanza
e) update grub
f) shutdown the system
g) boot the buster grub and select the bullseye 11 rc1 boot stanza
present in 40_custom
bullseye rc1 now runs
