Hello all,

answering my own question here...

I uninstalled grub-efi-amd64-signed and re-ran update-grub. Now, no grub prompt. Things work.

Regards,

Hello all,

which package specifically (2.02+dfsg1-9) should be installed? There are quite a few in the Grub family.

Hi,

there is a 2.02+dfsg1-9 in Ceres, which introduced a change to not enforce signature check if Secure Boot is disabled (as it seems to be the case here). Could you please try it?

Thanks for the reply. Does not help me much though.

Irrespective of the grub directory being in the esp/efi.. tree, I am still stumped. Did you read the link I provided on other person's woes?

grub-efi-amd64 2.02+dfsg1-8 seems to be working correctly here. I rebooted into my ceres install, checked that the grub version was right and ran grub-install --bootloader-id=nodbus && update-grub.

This installation is on a single partition. No raid, lvm or encryption.

I haven't tried that yet, but I will let my ceres install take over the boot on this machine. Meanwhile, can you tell me how your grub directory got into the efi partition? The only file I have in any of the efi directories is grubx64.efi. My grub directory is a subdir of /boot, as it has always been.

Hello all,

after upgrading Ascii to Ceres (in situ), all went well for a week or so. Last week, after an apt upgrade, the abovementioned Grub version was installed. This leads to a Grub prompt after boot. Regress/fallback to Grub 2.02~beta3-5 does not help (Grub prompt). Anyone else experiencing same?

I have done the usual grub-install, update-grub stuff etc. with no (apparent) errors. See below -

LC_ALL=C grub-install --target=x86_64-efi --bootloader=devuan

Efibootmgr reports -

From the Grub prompt -

set pager=1
set root=(md/0)
linux /boot/vmlinux..... root=/dev/md0
initrd /boot/initrd...
boot

will bring the system up. For obvious reasons, I would prefer to avoid this.

It would seem I am not alone here -

Any pointers much appreciated.
