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 /etc/apt/sources.list，将 deb cdrom:这一行注释掉：
nano /etc/apt/sources.list也就是下面的第二行，注释掉
# deb cdrom:[Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130$ # deb cdrom:[Debian GNU/Linux 7.0.0 _Wheezy_ - Official amd64 CD Binary-1 20130$ deb http://ftp.us.debian.org/debian/ wheezy main deb-src http://ftp.us.debian.org/debian/ wheezy main deb http://security.debian.org/ wheezy/updates main deb-src http://security.debian.org/ wheezy/updates main # wheezy-updates, previously known as 'volatile' deb http://ftp.us.debian.org/debian/ wheezy-updates main deb-src http://ftp.us.debian.org/debian/ wheezy-updates main推荐站内搜索：香港空间哪个好、域名 注册、韩国服务器推荐、域名信息查询、域名备案查询、注册 域名、美国服务器租用网站、外网ip地址、香港服务器、淘宝虚拟主机、
