This week, on 26 Feb I did apt-get upgrade and apt-get dist-upgrade then it displayed me a blue window with a prompt to install grub, because it can't find it. I pressed 'cancel', because I was a bit wonder. My previous successful upgrade was 8 Jan 2019. Is this a known issue? Why it doesn't see my device?
When was the previous upgrade ?In January there was a regression in udev which messed symlink names generated in /dev/disk/by-id/, which are used to identify which device GRUB was installed on. But the regression has been fixed since then.
Now I have in grub-emu: error: no such device: dff08b74-3e1a-46b2-aef7-d1c77b14d098. Loading Linux 4.19.0-2-amd64 ... error: can't find command `linux'. Loading initial ramdisk ... error: can't find command `initrd'. Press any key to continue... Failed to boot both default and fallback entries.
Did you run grub-emu as root ? I get the same error message if I run it as a standard user.
