新手推荐使用图形界面配置： 系统设置 -> 软件和更新 选择下载服务器 -> "mirrors.aliyun.com"

终端命令更改

root用户登录

用编辑器打开：/etc/apt/sources.list

替换 http://archive.ubuntu.com/

为 mirrors.aliyun.com

或者 mirrors.163.com

ubuntu 18.04配置如下

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
