I run Bullseye on an UEFI boot machine. The system originally ran on
BIOS boot hardware, but this summer I moved it to an UEFI machine by
installing the EFI version of grub.
This has worked fine since then, with unattended-upgrades succeeding in
keeping it up-to-date, including kernel upgrades and reboots.
But this morning, unattended-upgrades failed:
Packages that attempted to upgrade:
grub-common grub-efi-amd64-bin grub-efi-amd64-signed grub-pc
grub-pc-bin grub2 grub2-common
Packages with upgradable origin but kept back:
Debian oldstable-security:
grub2-common grub-common grub-pc-bin grub-efi-amd64-signed grub2
grub-pc grub-efi-amd64-bin
(The entire mail from unattended-upgrades is quoted below.)
It seems to have a problem with "grub-pc". But I thought that grub-pc
was only for BIOS boot, and that by installing the UEFI version grub-pc
would disappear or at least be disabled.
Do I need to do an uninstall of grub-pc? and will that not be dangerous
for the EFI version?
I am now somewhat worried - can my system boot at all? And I expect
that the point release will be installed tonight - will that mess things
up further? Can I simply disable unattended-upgrades with systemctl in
order to temporarily stop unattended upgrades?
This machine is also my router/firewall/server, so if it fails,
everything becomes difficult.
Thanks for any help you can offer,
Jesper
