$ vagrant up The provider 'virtualbox' that was requested to back the machine 'scdev' is reporting that it isn't usable on this system. The reason is shown below: VirtualBox is complaining that the installation is incomplete. Please run `VBoxManage --version` to see the error message which should contain instructions on how to fix this error.
Then I tried to investigate and seems like I already have those packages:
$ VBoxManage --version WARNING: The character device /dev/vboxdrv does not exist. Please install the virtualbox-dkms package and the appropriate headers, most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed. 5.0.24_Ubuntur108355 $ sudo apt install linux-headers-generic Reading package lists...
