使用命令
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #备份源文件
sudo vim /etc/apt/sources.list #修改源文件
sudo apt-get update #更新列表
配置源文件
将 sources.list 文件内容替换如下
deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
Ubuntu 版本
不同 ubuntu 版本，源配置不太相同，对照下面表格替换文件中相应位置
| Ubuntu version | Repository |
|---|---|
| Precise 12.04 (LTS) | deb https://apt.dockerproject.org/repo ubuntu-precise main |
| Trusty 14.04 (LTS) | deb https://apt.dockerproject.org/repo ubuntu-trusty main |
| Wily 15.10 | deb https://apt.dockerproject.org/repo ubuntu-wily main |
| Xenial 16.04 (LTS) | deb https://apt.dockerproject.org/repo ubuntu-xenial main |
比如 16.04 版本,执行以下命令
sudo vim /etc/apt/sources.list # 打开源配置文件
:%s/trusty/xenial/g # 执行vim命令>>全局替换trusty为xenial
:wq! # 保存文件并退出
sudo apt update && sudo apt upgrade # 更新软件源并升级可更新软件（非必须执行）
