无法删除或安装内核
我不小心删除了我的/boot分区，但我能够用grub-install取回它
我正试图通过本指南再次chroot并安装内核： 如何在意外删除所有内核后恢复系统？
但是，当我尝试删除或安装包时，我收到以下错误：
root @ ubuntu：/＃apt-get install -f

更新：似乎卡在以下命令上

我怎样才能解决这个问题？
上面有一个提示无法处理有关postinst.d因此我查看了它运行的脚本并找到了它们。
我做了一个rm -rf /var/lib/dpkg/info/linux-image-4.2.0-25-generic.* ，其中包含一些正在使用的.postrm和.list文件，这些文件因任何原因都有问题。 我删除了它们，运行dpkg --configure -a并且不再重新安装错误！ 好极了。 谢谢大家指出我正确的方向。 还有一个关于重新安装grub的提示，我在Boot Repair中做了一些提示，之后我能够更好地查明事情被破坏的地方。
