更换方法
Ubuntu采用apt作为软件安装工具,其镜像源列表记录在/etc/apt/source.list文件中。
首先将source.list复制为source.list.bak备份,然后将source.list内容改为需要的镜像源列表即可。
修改完成后保存source.list文件,执行:
sudo apt update
等待更新完成即可。
常用国内镜像源
本节均为 Ubuntu 20.04 的镜像源列表。若为其他版本,将所有focal更改为其他版本代号即可。
常用的Ubuntu版本代号如下:
Ubuntu 22.04:jammy
Ubuntu 20.04:focal
Ubuntu 18.04:bionic
Ubuntu 16.04:xenial
