System stuck on grub command prompt after apt update and restart - empty grub.cfg #259

Hi there,

After running apt update that included a kernel update, the system cannot boot after a restart and is stuck on the grub command prompt. After some checks I noticed that 'grub.cfg' in '/boot/grub/' (same dir contains 'grub-btrfs.cfg') is empty. Some info on the setup and grub parameters:

OS: Linux Mint 20.1
root=hd0,gpt3
prefix=(hd0,gpt3)/@/boot/grub
grub_pltaform=efi
package_version=2.04-1ubuntu44.2

Please advise.

Not sure if that is a problem of grub-btrfs, since we only append something to the grub.cfg. Looks like your grub config generation is broken. I guess you are in a live system now? Can you chroot into your system and run grub-mkconfig?
