  • Try: Install the virtualbox-dkms package on your Ubuntu host (not guest) – user535733 Dec 02 '20 at 17:02

    Open your terminal and cut/paste this: sudo apt-get install dkms build-essential linux-headers-generic -y ; sudo apt-get install linux-headers-$(uname -r) -y; sudo apt install --reinstall virtualbox -y – KGIII Dec 02 '20 at 18:12
  • Did the above resolve your VirtualBox issue? If so, you'll want to keep that command copied and ready for the next time the kernel updates. You'll need to re-run it every time, but it only takes a few minutes. If it did resolve your issue, I'll write out a more complete answer to explain it. – KGIII Dec 03 '20 at 03:06
  • I tried sudo apt-get install dkms build-essential linux-headers-generic -y ; sudo apt-get install linux-headers-$(uname -r) -y; sudo apt install --reinstall virtualbox -y but still there is a persistent problem with dkms: output – xpslos Dec 12 '20 at 19:24
  • Does this answer your question? Virtualbox Kernel driver not installed – karel May 09 '21 at 04:19
