Debian升级、安装时出现提示磁盘插入的问题解决
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$
