Debian 8安装可能会出现的问题

apt-get提示磁盘插入

apt-get时会出现类似以下错误
Media change: please insert the disc labeled 'Debian GNU/Linux 7.3.0 _Wheezy_ - Official i386 DVD Binary-1 20131215-03:40' in the drive '/media/cdrom/' and press enter

解决方案：
修改文件 sudo nano /etc/apt/sources.list，将 deb cdrom:这一行注释掉，如

没有安装sudo

  1. 打开终端
  2. 切换到root用户
    • 执行 su 命令
    • 输入密码
  3. 安装sudo
    • apt-get install sudo
  4. 将用户添加到sudo group
    • adduser yourusername sudo
  5. 将用户名添加到 /etc/sudoers 文件
    • 执行 nano /etc/sudoers
    • 找到 %sudo ALL=(ALL:ALL) ALL 这一行
    • 在下面插入 yourusername ALL=(ALL:ALL) ALL (这句话好奇怪)
    • 保存
  6. OK了
