我正在尝试在 BunsenLabs (Debian) 系统上安装 virtualbox。
我确认我已安装所有内容：
$ sudo apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') virtualbox dkms virtualbox-dkms
Reading package lists... Done
Building dependency tree
Reading state information... Done
dkms is already the newest version.
linux-headers-amd64 is already the newest version.
virtualbox is already the newest version.
virtualbox-dkms is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
（要升级的包是openjre-8-headless）。
但是，当我开始时virtualbox：
$ virtualbox
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate
headers, most likely linux-headers-amd64.
You will not be able to start VMs until this problem is fixed.
重新安装一切，重新配置一切。
尝试强制创建设备也失败：
$ sudo modprobe vboxdrv
modprobe: FATAL: Module vboxdrv not found.
我应该手动创建设备吗？我还有什么其他选择？
答案1
卸载 debian 版本的virtualbox和后virtualbox-dkms，我添加了Oracle 的存储库：
#Add the repository
sudo echo "deb http://download.virtualbox.org/virtualbox/debian jessie contrib" > /etc/apt/source.list.d/virtualbox.list
#Add the key
curl https://www.virtualbox.org/download/oracle_vbox_2016.asc
sudo apt-key add oracle_vbox_2016.asc
然后安装了这个virtualbox-5.1包，效果很好。
