This broke starting a graphical desktop environment in VirtualBox when upgrading Whonix 15.0.0.3.3 from Whonix stable repository.
sudo modprobe vboxdrv
modprobe: ERROR: could not insert ‘vboxdrv’: Required key not available
Upstream bug reports:
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=935961
- #11577 (Secure Boot doesn't allow 'vboxdrv' module to load (now works for Ubuntu and Debian 10+ hosts)) – Oracle VM VirtualBox
Will therefore revert.
Fixing this for real should be possible by either just signing the VirtualBox guest additions modules:
- GitHub - ivan-californias/vbox-sign-modules: Scripts for signing virtualbox kernel modules
- maj-scripts/vboxsign at master · majal/maj-scripts · GitHub
- Signing VirtualBox Kernel Modules · GitHub
Or better a more generic solution of signing all DKMS modules:
Once this is sorted, can be re-enabled.
