╃苍狼山庄╃在升级Debian7的系统内核时，碰到了“depends on libc6 (>= 2.14); however:”错误，详细错误信息如下：

因libc6版本太低导致linux-headers-4.9.47-040947-generic安装失败，并且MySql WorkBench, Eclipse-4.4等很多常用开发工具都要求 glibc 版本 >= 2.14，而 Wheezy 仓库中 glibc 最高仅为 2.13。为了让这些工具正常使用，我们只能用 Wheezy unstable 版的 glibc。
升级方法如下：
在/etc/apt/sources.list 文件中添加软件源：
# 注意：下面这两条源只需要添加一个就可以，根据自己服务器选择 # 下面这行添加的是国内镜像，如果是国内服务器建议用这个 echo "deb http://mirrors.ustc.edu.cn/debian sid main" >> /etc/apt/sources.list # 下面这行是官方的，如果是国外服务器建议用这个 echo "deb http://ftp.debian.org/debian sid main" >> /etc/apt/sources.list
添加完成后执行:
apt-get update apt-get -t sid install libc6 libc6-dev libc6-dbg
即可自动安装 glibc 至新版本。
[info_box]注意：安装完成后务必将上面新添加的源从 sources.list 中删除，否则你下次再 apt-get install 其它软件的时候，apt-get 就会提示你要删除一大片库文件，如果你选择了Y，gnome桌面就被删掉了。[/info_box]
