I'm running ubuntu 18.04, I installed virtual box from ubuntu software and it was out of date, so I dowloaded the latest version from their website and now when I try to run a virtual machine it comes up with errors like this: enter image description hereFailed to open a session for the virtual machine win 10.

The virtual machine 'win 10' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005) Component: MachineWrap Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}

    The error message is correct; "Make sure that you are not mixing builds of VirtualBox from different sources" - your kernel modules will be for the Ubuntu installed version, the program the Oracle supplied version. By replacing the default Ubuntu version you'll have to update it yourself to remain secure (ie. you've chosen not to rely on the Ubuntu version which has security patches backported to it) – guiverc Jul 5 at 8:00
