There were problems setting up VirtualBox.  To re-start the set-up process, run

  /sbin/vboxconfig

as root.  If your system is using EFI Secure Boot you may need to sign the

kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load

them. Please see your Linux system's documentation for more information.

Errors were encountered while processing:

 virtualbox-6.1

Processing was halted because there were too many errors.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Can somebody explain how to solve this problem. Thank you!

This can happen on occasion. Fortunately, it's not too tricky to fix. Follow these steps:

First, find out what process is using the file:

sudo fuser -v /var/cache/debconf/config.dat

You'll see something like this:

USER        PID ACCESS COMMAND /var/cache/debconf/config.dat:
root       8440 F.... frontend

Take the PID value and put an end to it:

sudo kill <PID>
sudo kill -9 <PID>

This will unlock the config.dat file. From there you'll be able to remove VirtualBox:

sudo apt purge virtualbox-6.1
sudo apt purge virtualbox-dkms 

Hope this gives you what you need.
