当我输入grub-customizer终端时出现错误消息
localuser:root being added to access control list
Unable to init server: Could not connect: Connection refused
(grub-customizer:14287): Gtk-WARNING **: 13:32:45.674: cannot open display: localuser:root being removed from access control list
我尝试过但没有奏效的方法：
1-我删除了 grub 定制器并重新启动电脑，然后再次下载。
2-我尝试通过终端而不是 ubuntu 软件下载
（Ubuntu 版本 21.10）
