I installed virtualbox using the official instruction on the oracle virtualbox website here: https://www.virtualbox.org/wiki/Linux_Downloads
I followed the method of adding the package source to my repositories. I am doing this rather than using the default installation from the ubuntu package repositories because I need to use a VM created in a newer version of virtualbox.
Installation went fine, except that virtualbox asks to rebook so you can register it with UFEI (sorry I don't know the correct jargon here). I dutifully rebooted, but was distracted and unfortunately missed the screen where you are prompted to do this at boot. Now I can't get the screen back, and when I try to uninstall vitualbox I get:
$ sudo apt-get remove virtualbox-6.1

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
E: Sub-process /usr/bin/dpkg returned an error code (1)
and it won't let me uninstall.
I then tried following the advice in the error message an rerunning /sbin/vboxconfig, but this fails with
$ sudo /sbin/vboxconfig

What I really want is to again trigger the process of signing the kernal modules (or whatever) can anyone tell me how to do this?
