在进行apt-get升级或安装apt-get时出错

Question

当我试图在Debian9.0服务器上安装或升级任何东西时，我遇到了一个错误。

这就是终点站给我的。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cdebconf : Depends: libdebian-installer4 (>= 0.110) but it is not installed
            Depends: libtextwrap1 but it is not installed
 libc-bin : Depends: libc6 (< 2.25) but 2.28-10 is installed
 libc-dev-bin : Depends: libc6 (< 2.25) but 2.28-10 is installed
 libc6-dev : Depends: libc6 (= 2.24-11+deb9u4) but 2.28-10 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

有人知道怎么修吗？

我很抱歉地告诉你，你的系统可能坏到了无法合理修理的地步。为了追溯工作以确定发生了什么，您说您正在运行Debian 9系统，但是您的libc6包是从Debian 10 (2.28)安装的--这通常是由于试图混合来自多个版本的Debian或Debian衍生工具(如Ubuntu )的use而引起的。Debian的wiki在这个主题上有一些话要说：

不要使FrankenDebian Debian稳定，不应该与其他版本相结合。如果您正在尝试安装当前Debian稳定版本中不可用的软件，那么为其他Debian版本添加存储库并不是一个好主意。问题可能不会马上发生，但下次安装更新时。之所以会出现故障，是因为为一个Debian版本打包的软件是为兼容该版本的其他软件而构建的。例如，在拉伸系统上安装buster软件包也可以安装较新版本的核心库，包括libc6。这导致一个系统不是测试或稳定的，而是两者的组合破裂。

在这个阶段，您最好的选择可能是备份数据并重新安装操作系统，这一次要确保没有任何存储库试图从不适合Debian 9的存储库中提取。
