I'm running Xubuntu 20.04 (with current updates) and have the boinc-virtualbox (7.16.6+dfsg-1) package installed via Synaptic from the Ubuntu Software repository.
And I get this message every time I boot the machine:
vboxdrv: module verification failed: signature and/or required key missing - tainting kernel
The module still seems to load, but I'd like to eliminate the error message that appears on my screen.
Is there a way I can accomplish this?
