Status changed to 'Confirmed' because the bug affects multiple users.

[Shane O'Sullivan (hitsuji)]

removing the case clause terminator ";;" on line 19 of /var/lib/dpkg/info/grub-efi-amd64-signed.postinst allowed the installation to continue for me and complete the installation

Thanks @hitsuji that adjustmnet worked for me as well.

[Shane O'Sullivan (hitsuji)]

looks like the original code in the debian postinst wraps what results in line 19 in sub case statement.

case @PACKAGE@ in
  grub-efi-ia32) target=i386-efi ;;
  grub-efi-amd64) target=x86_64-efi ;;
  grub-efi-ia64) target=ia64-efi ;;
  grub-efi-arm) target=arm-efi ;;
  grub-efi-arm64) target=arm64-efi ;;
esac

since the package of for amd64 only then the case block is removed, but the clause terminator has accidentally been left behind and needs to be removed
