latest update & virtualbox

[Jack Dangler]

Good morning, all.

After my last updates/reboot, I'm getting an error attempting to load a 
previously built (known good) virtual machine on my virtualbox 
installation. My host looks like -

$ sudo uname -a
Linux jackNest-Pavilion-15-eg00025nr 6.5.0-17-generic #17~22.04.1-Ubuntu

I can launch the app, but attempting to start any virtual machine 
produces "kernel driver not installed (rc=-1908). It instructs to setup 
by executing:

'sbin/vboxconfig'

upon running this, I get a different issue -

sudo /sbin/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: You must sign these kernel modules before using VirtualBox:
   vboxdrv vboxnetflt vboxnetadp
See the documentation for your Linux distribution..
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: Signing VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find 
out why.

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.

Looking at the detail modprobe attempt, executing that command (modprobe 
vboxdrv) returns -

sudo modprobe vboxdrv
modprobe: ERROR: could not insert 'vboxdrv': Key was rejected by service

With the last updates, I do recall being asked about EFI Secure Boot, 
but have not used it before, so I'm not quite sure what to do with it. 
Any input is appreciated.

Regards

Jack
