1. ubuntu 18.04

After the Ubuntu 18.04 AMD64 corresponding to the virtualbox is installed, the startup of virtualbox does not respond. After a flash, the startup fails

2. Direct command line start

Find the command cd /usr/bin
Start / usr / bin $. / VirtualBox

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (4.15.0-33-generic) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /sbin/vboxconfig

         You will not be able to start VMs until this problem is fixed.
VirtualBox: Error -10 in SUPR3HardenedMain!
VirtualBox: Effective UID is not root (euid=1000 egid=1000 uid=1000 gid=1000)

VirtualBox: Tip! It may help to reinstall VirtualBox.

Then execute / usr / bin $sudo / SBIN / vboxconfig, which is still not easy to use, and continue to report mercilessly

sudo: /sbin/vboxconfig: command not found

3. restoration

After that, I wanted to check the version number of the software. To install a version viewing tool / usr / bin $sudo apt get install apt show versions, the result is as follows:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 virtualbox-5.2 : Depends: libcurl4 (>= 7.16.2) but it is not going to be installed
                  Depends: libqt5opengl5 (>= 5.0.2) but it is not going to be installed
                  Depends: libqt5printsupport5 (>= 5.0.2) but it is not going to be installed
                  Depends: libqt5x11extras5 (>= 5.6.0) but it is not going to be installed
                  Depends: libsdl1.2debian (>= 1.2.11) but it is not going to be installed
                  Recommends: libsdl-ttf2.0-0 but it is not going to be installed
                  Recommends: gcc but it is not going to be installed
                  Recommends: make or
                              build-essential but it is not going to be installed or
                              dpkg-dev but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

In this case, execute / usr / bin $sudo apt -- fix broken install honestly
And then there's a lot of stuff, and finally

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

Then run as root

/sbin/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.

After that, you can start virtualbox from the win key. I wonder if your problem has been solved
