UPDATE: Uh, I'm an idiot.
The problem was that, when adding my local partitions to /etc/fstab, I did not just modify fstab but copied it in from another system (on another partition of the same computer). The result was that the computer booted one disk, read fstab ... and saw that the root volume in fstab was not the same as the one it had just booted.
You can skip the rest. My bad, sorry.

Yesterday, I installed a new 24.04 system (in fact, two) and yesterday it worked just fine. But this morning, I could not boot it. Fortunately, I have another system on another partition. When I try to boot it (going thru reFind, which works fine for my other, older system), I get the messages shown in the image. Then it hangs.
I have looked at all my disk partitions and there is no UUID=668... anything anywhere. (sudo file -sL /dev/sd,,,,)
I do not know why it is talking about Raid as I have none.
I cannot find or at least boot to any grub entry which displays anything of interest. I tried
sudo grub-install /dev/sda
sudo update-grub
sudo grub-install /dev/sdb
all to no avail. The list of possible boot sources given by my bios looks like this.
I have tried them all. Aside from the refind entry, they either reboot, reboot to bios config, or display a black screen of death. Refind finds some grub.cfg entries, but they also hang.
For info, my disks are sda (Kingston SV3...), sdb (PNY CS900...) and sdc (ST1000..., which contains no bootable system).
