hostnamectl 命令導致 Failed to create bus connection: No such file or directory

我正在遵循本指南，但遇到了問題。 https://www.tecmint.com/initial-ubuntu-server-setup-guide/

我正在嘗試在 wsl2 中的 Ubuntu 中創建一台 linux 機器，然後使用它重命名它hostnamectl但出現錯誤

Failed to create bus connection: No such file or directory

我試圖遵循這些解決方案。

該解決方案建議安裝我所做的軟體包。 如何解決 hostnamectl 命令的問題。它無法連接到 dbus

不幸的是，涉及使用的其他解決方案strace表明我的問題不是其他解決方案可以解決的符號連結問題。

hostnamectl 顯示錯誤：“無法創建匯流排連接：沒有這樣的文件或目錄”

問題的核心hostnamectl是 systemd 實用程序，它作用於 systemd-hostnamed.service。WSL 目前不提供對 systemd 的支持。

此外，WSL 將主機名設置為託管實例的 Windows 電腦的名稱。雖然您可以通過更改 Windows 主機名 ( Control Panel-> System-> See the name of this computer-> Change Settings) 來更改它，但您不能更改 WSL 主機名本身。

除了遵循您連結的教程之外，您更改主機名的最終目標是什麼？也許有更好的解決方案（例如更改提示）。
