grub-efi-amd64 64签名包安装后脚本子进程返回错误退出状态127

Question

我的双引导笔记本电脑运行Ubuntu18.04.3作为我的主要操作系统升级后，也与Windows。每当我试图安装或更新应用程序时，都会遇到以下错误：

Setting up grub-efi-amd64-signed (1.128+2.04-1ubuntu12) ...
dpkg: error processing package grub-efi-amd64-signed (--configure):
 installed grub-efi-amd64-signed package post-installation script subprocess ret
urned error exit status 127
Errors were encountered while processing:
 grub-efi-amd64-signed
E: Sub-process /usr/bin/dpkg returned an error code (1)

现在，这发生在任何交互apt，这是非常不方便的。我已经尝试更新grub，但是没有任何解决方案。

这是我的dpkg和f吧，如果有什么帮助的话。

根据这个错误报告，您需要安装mokutil来解决问题。

这个包似乎缺少依赖关系。
