恢复 GRUB 引导加载程序 -

我刚刚进入 Linux 世界，所以请不要对我讲太多技术性的东西。

我曾尝试在 Ubuntu20.04 LTS 上安装 Windows10。我参考了以下视频：[https://www.youtube.com/watch?v=bzbIckBnerg&list=WL&index=16&t=542s][1] 一切顺利，直到引导修复安装才能恢复 GRUB 引导加载程序。我使用的命令如下：

sudo add-apt-repository ppa:yannubuntu/boot-repair

我收到的信息如下：

我不知道发生了什么事。如果你能帮助我，我将非常感激。

问候。

似乎您正在使用 Ubuntu 19.04（已终止使用）的安装程序来完成这项工作，这就是罪魁祸首。

根据https://launchpad.net/~yannubuntu/+archive/ubuntu/boot-repair 没有提供disco(19.04) 的包裹。

你需要从以下网址下载最新版本的 Ubuntuhttps://ubuntu.com/#download并创建一个新的安装程序 USB。
