Ubuntu更换软件源 重要：备份原始软件源


重要：备份原始软件源

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

1.首先切换到root用户
su root
初学者需要先创建root
使用:sudo passwd root设置root的密码，然后再切换

2.用文本编辑器打开sources.list,手动更换新源
vi /etc/apt/sources.list
或者 gedit /etc/apt/sources.list
没有vi 或 gedit 直接用apt install 命令（apt-get 命令也可以）

  1. 确定自己安装的系统版本号
    lsb_release -a

    将 下面软件源的 trusty 替换为你的版本号
