[Bug 1739853] [NEW] package grub-efi-amd64-signed 1.66.14+2.02~beta2-36ubuntu3.14 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Patrick N. Wines]

Public bug reported:

I had a problem with Samba and winbind that I couldn't sort so tried to
install a newer version alonside the existing.  Got grub error.

I may have fixed it by going into recovery  ode and selecting the grub
fix option.
