ubuntu apt-get 更换清华源设置
ubutun agt-get 清华源地址为:https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
1.备份ubuntu 中/etc/apt/sources.list
sudo cp sources.list sources.list.bak
2.编辑sources.list
选择ubutun对应的系统版本(我用的是 ubutun 16.04 LTS),拷贝对应内容覆盖sources.list文件:
# 默认注释了源码镜像以提高 apt update 速度,如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
