On updating one of my sandbox hosts from tw 20241010 to 20241119 level, reboot failed, throwing me into the dreaded grub rescue shell with this message:

> error: ../../grub-core/kern/dl.c:382:symbol 'grub_is_cli_need_auth' not found.

The system has two disks, gpt formatted, sda1+sdb1 as "BIOS boot" partition for grub and sda2+sdb2 a RAID1 with LVM inside.

Nothing unusual was seen on zypper dupping (I think... sorry, output not kept).

I could repair the boot by rescue booting and running "grub2-install /dev/sda ; grub2-install /dev/sdb".

Questions remaining:
1) isn't that supposed to work without manual intervention / rescue+grub2-install run?
2) general issue or something maybe related to my own setup (no fresh install for several years)

Anything I could check to further understand this / hints on what I might do wrong?

best regards

Patrick
