1.找一个国内的镜像源
比如清华大学的ubuntu1604镜像源:
# 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
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
2.备份系统的现有镜像源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
3. 更新源服务器列表
就是修改镜像源文件里面的内容:
vim /etc/apt/sources.list
然后删除之前的,把清华大学的粘贴上去
4.Ubuntu软件操作的相关命令
sudo apt-get update 更新源
sudo apt-get install package 安装包
sudo apt-get remove package 删除包
