在 ubuntu 19.10 上安装引导修复时出错

Question

我在 grub 启动初始化程序上遇到了问题。

当我通过 live CD 将引导修复安装到 Ubuntu 19.10 时，出现以下错误。

ubuntu@ubuntu:~$ sudo apt install boot-repair
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 boot-repair : Depends: boot-sav but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
ubuntu@ubuntu:~$ 

谁能帮我？

Answer 1

一些依赖项来自 Universe 存储库。启用它，然后重试：

sudo add-apt-repository universe

Answer 2

先试试sudo fix broken packages吧。但它可能不起作用。

我遇到过破损的包裹，但这个方法不起作用。但在另一台电脑上它可以工作。我实在不明白为什么会这样。
