The same here. You should be more careful when upgrading or fixing a security issue in the boot loader. It currently breaks a Debian Buster system, which is production. The suggested grub reinstall method did _not_ work for me. I booted from a USB stick into rescue mode and had to downgrade grub-common package (I don’t have grub2 on my system) and reinstall all dependent packages again. After downgrading grub-common/grub2-common to version 2.02+dfsg1-20, my system boots and works fine.

Downgrade grub-common/grub2-common:

from: 2.02+dfsg1-20+deb10u2
to:2.02+dfsg1-20

and it did work after reboot.


See my APT history log for details.
