I thought I followed the instructions correctly however something has gone awry.
Everything says VB 7 is loaded okay but when I try to start my Linux guest o/s I get the following error.
The initial 6.138 VB was installed from the Linux Zorin 16.2 (ubuntu 20.04)options then updated ti now.
This update was from the VB official download page selecting ubuntu 20.04

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.
~$ sudo /sbin/vboxconfig

How do I correct please?
RTR3InitEx failed with rc=-1912 (fRtFlags=0x10000) (rc=-1912)
The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing
'/sbin/vboxconfig'
may correct this. Make sure that you are not mixing builds of VirtualBox from different sources.
