Ran into this after upgrading work computer from trusty to xenial. Tried all possible install alternatives for VirtualBox (official and repos), but module always refused to load.
In the end, as a hopefully temporary solution, disabled validation, booted, confirmed to disable secure boot and voila, everything loads. Not a very optimal solution, really the modules should just be signed for kernel 4.4. This is what I did: > sudo sudo mokutil --disable-validation Curiously, after boot and confirming to disable secure boot, UEFI still shows it enabled and so does `sudo mokutil --sb-state`.. Some kind of "enabled but not validating modules" state? -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
