I have on my computer Windows 10 and Ubuntu 18.04.04 LTS in dual boot with Grub. EFI and Secure boot are enabled in BIOS.
I would like to uninstall Virtualbox in order to install a new version (>6.1) having no issues with my Linux kernel but I'm not able to do it.
Thus, when I run sudo apt-get remove virtualbox-6.0, I get :
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following package was automatically installed and is no longer required:
libsdl-ttf2.0-0
Use 'sudo apt autoremove' to remove it.
The following packages will be REMOVED:
virtualbox-6.0
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
After this operation, 228 MB disk space will be freed.

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-6.0
E: Sub-process /usr/bin/dpkg returned an error code (1)
And when I do fuser -v /var/cache/debconf/config.dat, I don't see any processus, nothing.
Would you know why is there this error exactly please ? And how to fix it so that I can reinstall VirtualBox 6.1 ? If possible, without desactivating secure boot and EFI.
Thank you in advance for your help. Best regards
