更新后出错

更新后出错

你好我有 Ubuntu 20.04,并且安装了 grub-customizer 这 2 个命令:第一:-sudo add-apt-repository ppa:danielrichter2007/grub-customizer和第二:-sudo apt install grub-customizer安装后,它运行良好,但每次我通过终端输入此命令进行更新时,命令sudo apt update都会给出此输出:-

Ign:8 http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu focal InRelease
Err:9 http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu focal Release
  404  Not Found [IP: 91.189.95.85 80]
Reading package lists... Done
E: The repository 'http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

我不知道这是什么原因,但我想解决它。谢谢。

我根据此处作者网站上的说明安装了 grub 定制器。https://launchpad.net/grub-customizer从这一页开始

如何安装:

  • Ubuntu 19.10 或更新版本:只需运行sudo apt install grub-customizer- 存在于存储库
