Ubuntu是国外的网站，我们下载东西会非常的慢，这时我们需要更新源，更新成国内的，下载速度就蛮快的了
目录
- 1.输入命令修改sources.list文件，当然需要超级权限，所以要加sudo
- 2.编辑/etc/apt/sources.list文件
- 3.更新源
- 4.更新成功
- 附上源地址
1.输入命令修改sources.list文件，当然需要超级权限，所以要加sudo
sudo vim /etc/apt/sources.list
- 1
如果第一次安装Ubuntu还没有更新vim建议使用gedit修改
sudo gedit /etc/apt/sources.list
- 1
- 2
注意：最好备份一下这个文件，免得出错了回不去了
2.编辑/etc/apt/sources.list文件
在下面随便挑选一个下载源（博文最后列出，可直接复制）就可以了，这里以阿里源为例
vim版：
gedit版（记得点击save哦）：
3.更新源
sudo apt-get update
- 1
4.更新成功
