我正在尝试在我的系统上安装 Grub-Customizer，但是在添加 PPA 时我不断收到以下输出：
Adding deb entry to /etc/apt/sources.list.d/danielrichter2007-ubuntu-grub-customizer-lunar.list

Reading package lists... Done
E: The repository 'https://ppa.launchpadcontent.net/danielrichter2007/grub-customizer/ubuntu lunar 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.
最终，当我这样做时，sudo apt-get install grub-customizer它失败了。
我读到过一些文章说它最初由于逻辑错误而从 Ubuntu 22.04 中删除，但是这个问题已经修复了？
有什么办法可以将其安装到我的系统上吗？
谢谢！
