我正在尝试修复apt-get一台旧玩具机，以便可以再次安装程序包。
我得到这个之后sudo apt-get install -f：
$ sudo apt-get install -f

但是当我尝试安装时upstart-job我得到：

Note, selecting 'upstart' instead of 'upstart-job'
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
plymouth : Depends: mountall (>= 2.0) but it is not going to be installed

因为这是一台玩具机器，所以我愿意接受激进的方法/想法。
谢谢！

解决此问题的最简单方法是使用另一台机器（或者这台，如果可以的话）写入 Ubuntu Live 拇指驱动器，从该机器重新启动，然后选择“安装 Ubuntu”。
安装程序不会关心您是否有空白硬盘、损坏的 Ubuntu、损坏或正常运行的 Windows、损坏或正常运行的任何其他系统，只要硬件功能正常且有足够的存储空间（加上其余的系统要求），您几乎每次都会得到一个可以正常运行的系统（“几乎”只是因为有少数系统配备了某种不受支持的硬件）。
当然，如果您有需要保留的数据，请在开始之前备份这些数据。如果您将数据/home放在单独的分区上，这个过程会大大简化；即使（谨慎起见）您在重新安装后使用新的登录名，您输入的所有旧数据都/home将位于旧登录名下的文件夹中（或安全地保存在您的备份中）。
