在清华大学开源镜像站找到自己的linux系统版本
我的是Ubuntu 18.04LTS:

apt-get配置文件所在的目录为/etc/apt,故先进入目录,然后对原配置文件进行一份备份:sudo cp sources.list sources.list.bak,以防丢失。最后使用vim打开sources.list文件,将原内容删除,替换为新的配置内容(在root模式下进行)。备份命令如下:
ubuntu:~$ cd /etc/apt
ubuntu:/etc/apt$ sudo cp sources.list sources.list.bak
更新源,使配置生效
ubuntu:~$ sudo apt-get update
