问题
我尝试安装的所有软件包都无法安装，因为“insserv”和 virtualbox 存在问题。这可能是因为 VirtualBox，但我不知道是哪个部分导致了错误。我想知道是哪个部分（或者如果我错了，是 Ubuntu 中的哪个部分）导致了问题以及如何修复它。
信息
我不知道硬件信息是否重要，但可能重要。
软件+操作系统
我在 Ubuntu Xenial (16.04 LTS) 上安装了 VirtualBox 5.1 和扩展包。如果有必要的话，我安装了带 Guest Additions 的 Win XP Pro、FreeDOS 和 Puppy Linux (Racy)，全部都在 中~/VirtualBox VMs/。
如果这也很重要的话，通过上述 VBox 设置，我尝试获取 Fedora、Debian、OpenBSD、openSUSE、Kali 和 Linux Mint 的虚拟机。（可能还有更多，但我不记得了）
之前我安装了 VBox 4.3，但为了 5.1 而卸载了它。更早之前，我使用的是 Ubuntu Trusty (14.04.4 LTS) 和 VBox 4.3。两者都只有 Win XP Pro，没有客户添加程序。
硬件
Dell Precision M6300（是的，我已经老了），配有 NVIDIA G84GLM（Quadro FX 1600M）显卡、Broadcom BCM4312 802.11b/g LP-PHY（无线 1395 WLAN 迷你卡）以及一个未知的显卡，带有“适用于 Intel CPU 的处理器微码固件”驱动程序。

对于我没有从软件中心或安装 DVD（我仅用它来获取 Broadcom 驱动程序）获得的所有东西，这个问题一直存在。

日志显示此处BleachBit安装成功：

Dpkg 试图告诉您 virtualbox 软件包已安装，但未完全完成配置阶段。可能是 /var/lib/dpkg/info 中 virtualbox 的 postinst 脚本。主要故障如下：
insserv: script virtualbox: service vboxdrv already provided!
因此，该脚本尝试通过查看 /etc/init.d 脚本来注册 vboxdrv 以在启动时启动。我猜升级过程中出了点问题，遗留了一些文件。
您可以查看类似这样的资源https://wiki.debian.org/LSBInitScripts/DependencyBasedBoot并尝试进一步调试。我敢打赌 /etc/init.d 中有多个脚本包含“Provides: vboxdrv”标头。您可以在 /etc/init.d 中 grep 并找出哪一个是旧的。
您也可以尝试清除 virtualbox 包并重新安装它。
