在 Ubuntu 系统中,将 APT 源设置为阿里云源可以提高软件包更新和下载速度。你可以按照以下步骤操作:
1. 备份现有的源列表(可选,但推荐):
bash
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
2. 编辑 sources.list
文件:
使用以下命令打开 sources.list
文件:
bash
sudo nano /etc/apt/sources.list
3. 替换内容为阿里源:
根据你使用的 Ubuntu 版本,将内容替换为对应的阿里源。以下是常见版本的源地址:
-
Ubuntu 22.04 (Jammy):
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
-
Ubuntu 20.04 (Focal):
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
-
Ubuntu 18.04 (Bionic):
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
4. 保存并退出:
编辑完成后,按 Ctrl + O
保存文件,然后按 Ctrl + X
退出编辑器。
5. 更新软件包索引:
使用以下命令更新软件包索引:
bash
sudo apt update
完成以上步骤后,APT 已经使用阿里云源进行软件包的更新和下载。
