虚拟机的“流浪”问题

Question

$ vagrant up

The provider 'virtualbox' that was requested to back the machine
'scdev' is reporting that it isn't usable on this system. The
reason is shown below:

VirtualBox is complaining that the installation is incomplete. Please
run `VBoxManage --version` to see the error message which should contain
instructions on how to fix this error.

然后我尝试调查，似乎我已经有了这些包：

$ VBoxManage --version
WARNING: The character device /dev/vboxdrv does not exist.
 Please install the virtualbox-dkms package and the appropriate
 headers, most likely linux-headers-generic.

 You will not be able to start VMs until this problem is fixed.

这才几个月大，但我偶尔会遇到这个问题，我想为我的流浪汉发布解决方案/原因。

这个问题（对我来说）通常是由 Vagrant 意外结束引起的（读我的笔记本电脑电池没电了）。以下是对我有用的事情列表：

1. 一般来说，一个modprobe vboxdrv会做的伎俩。这会重新应用内核模块，一切都很好。
2. 或者，重新配置包 dpkg-reconfigure virtualbox-*
3. 最坏的情况，把它全部吹走，然后再试一次 sudo apt-get remove --purge virtualbox-dkms linux-headers-generic; #etc
