Ubuntu 22.04 (Jammy) 换源 ​

Ubuntu 22.04 LTS（代号 Jammy Jellyfish）更换为国内镜像源可以显著提升软件包下载速度。

快速换源步骤 ​

1. 备份原文件 ​

在修改前，先备份原始的 sources.list 文件：

bash
cp /etc/apt/sources.list /etc/apt/sources.list.bak

2. 编辑 sources.list 文件 ​

清空 sources.list 文件中的内容，然后将以下任何一个源复制到文件中：

bash
vim /etc/apt/sources.list

或使用 nano 编辑器：

bash
sudo nano /etc/apt/sources.list

3. 更新软件源 ​

保存文件后，执行以下命令更新软件源：

bash
sudo apt-get update
sudo apt-get upgrade

注意事项 ​

提示

  • 如果不需要源码包，可以删除或注释掉 deb-src 开头的行
  • jammy-proposed 仓库包含测试中的软件包，建议按需启用
  • 如果遇到 GPG 错误，可能需要导入相应的密钥

恢复原始配置

如果换源后出现问题，可以使用以下命令恢复原始配置：

bash
sudo cp /etc/apt/sources.list.bak /etc/apt/sources.list
sudo apt-get update
