如何重新运行启动加载程序？
运行sudo apt-get -f install说The link /vmlinuz.old is a damaged link并且：
you may need to re-run your boot loader[grub]
这是完整的输出：

如何重新运行引导加载程序？
根据womble 在内核卸载后对Damaged / vmlinuz和/initrd.img符号链接 的回答 （在服务器故障上 ），当你的引导加载程序是GRUB / GRUB2时，你不必在这种情况下做任何事情 – 就在这里。
对于其他一些引导加载程序（至少是LILO ），显然有时需要手动运行引导加载程序的配置。
如果你确实需要告诉GRUB检查现有内核并更新其配置，那么运行sudo update-grub会这样做。 运行它没有害处。 但在这种情况下，它不应该是必要的。
在grub的情况下，错误有点奇怪。
当apt安装一个新的内核版本时，它将/ vmlinuz和/initrd.img移动到/vmlinuz.old和/initrd.img.old（然后它仍然指向当前活动的内核。再次注意.old扩展名，这与“内核卸载后损坏的链接”中链接的故事不同，并创建了两个新文件/ vmlinuz /initrd.img。
当您运行apt-get autoremove （消息不是由apt-get -f install生成）时，它会删除以前活动的内核（在安装之后重新启动，在运行autoremove之前，对吗？），这会使链接无效。
当内核本身被删除时，autoremove本身会调用update-grub：
run-parts: executing /etc/kernel/postrm.d/zz-update-grub 3.13.0-32-generic /boot/vmlinuz-3.13.0-32-generic
因此：
The link /vmlinuz.old is a damaged link Removing symbolic link vmlinuz.old you may need to re-run your boot loader[grub]
所以，autoremove做：
- 删除旧内核
- 运行update-grub
- update-grub删除链接到已删除文件的.old文件。
没什么好担心的 ：-）
问候。
$ sudo update-grub
如果你想删除/清除旧包，你也可以
$ dpkg --list |grep "^rc" | cut -d " " -f 3 | xargs sudo dpkg --purge
