I just upgraded my system yesterday, which meant an updated grub, which meant grub-install was run again, which meant this happened to me again. Now on Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-150-generic x86_64) with grub2 2.02~beta2-36ubuntu3.22 and its dependencies. Then I found that Alejandro Mery's script in #17 worked for me.
