更換方法

Ubuntu採用apt作為軟體安裝工具，其映象源列表記錄在/etc/apt/source.list檔案中。

首先將source.list複製為source.list.bak備份，然後將source.list內容改為需要的映象源列表即可。

修改完成後儲存source.list檔案，執行：

sudo apt update

等待更新完成即可。

常用國內映象源

本節均為 Ubuntu 20.04 的映象源列表。若為其他版本，將所有focal更改為其他版本代號即可。

常用的Ubuntu版本代號如下：

  • Ubuntu 22.04：jammy
  • Ubuntu 20.04：focal
  • Ubuntu 18.04：bionic
  • Ubuntu 16.04：xenial

Ubuntu 通常採用“形容詞+小動物”作為版本代號（預設的桌布），在映象源列表中只有第一個詞。

此外，預設註釋了程式碼源以提高速度，註釋了預釋出軟體源（可能不穩定）。如有需要可以取消註釋。

建議將所有常用映象源儲存在/etc/apt目錄下，並命名為類似source.list.aliyun的形式，需要使用時直接複製替換source.list檔案即可。
