问题[archlinux]

事实是，我不小心将 MBR 转换为 GPT，现在我有了一个没有分区的半活磁盘。 Arch Linux LiveUSB 仅在紧急模式下启动，在此模式下没有包管理器或 fdisk 或 pared 等实用程序。如何通过 Arch Linux Live USB 紧急模式再次将 MBR 替换为 GPT？还有其他方法吗？我尝试了win10启动U盘，但提示磁盘错误。

我输入命令 - $ sudo date -s "2022-06-11 05:30:00"。系统不会更改时间。我究竟做错了什么？

当我在带有 I3 GUI 的 ArchLinux 上按Alt+时，我该怎么做才能截取屏幕截图？PrtSc

尝试在捆绑包上打开 GoLand 中的项目时Arch Linux + Wayland + SwayWM，会出现以下情况：

IDE 使用Toolbox App 1.17.7018, Arch Linux (Linux 5.7.6-arch1-1).

Arch Linux 为我崩溃了。如果我现在从 LiveUSB 启动，你能告诉我如何更新系统吗？

本质上，我需要pacman在本地操作系统上运行命令。
