Thanks for the info. This is not a bug, "Since Ubuntu kernel 4.4.0-20 the EFI_SECURE_BOOT_SIG_ENFORCE kernel config has been enabled. That prevents from loading unsigned third party modules if UEFI Secure Boot is enabled.
Since Ubuntu kernel build 4.4.0-21.37 this can be fixed by running sudo apt install mokutil sudo mokutil --disable-validation" Can we close this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574300 Title: Could not load 'vboxdrv' after upgrade to Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1574300/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
