Guys, I was in that trouble after upgrading to Xenial. Before vbox and vagrant worked well on my notebook. While upgrading I saw that secure boot was re-enabled (I do not remember enabling it). I followed some steps and solved this problem for me: 1. Disabled Secure Boot 2. Removed vagrant: sudo apt-get remove vagrant 3. Purged every vbox: sudo apt-get purge virtualbox-\* 4. Installed virtualbox-dkms I think that reconfiguring virtualbox-dkms and virtualbox will produce the same results whilst secure boot disabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1452827 Title: The character device /dev/vboxdrv does not exist.
