I had a similar issue with Ubuntu v.15.04, and the suggestion to delete /etc/init.d/vboxdrv worked. For good measure, I deleted all of the leftover vbox* binaries that were left in /etc/init.d, e.g.:
@billyJr:~$ ls /etc/init.d/vbox* /etc/init.d/vboxautostart-service /etc/init.d/vboxdrv /etc/init.d/vboxballoonctrl-service /etc/init.d/vboxweb-service waltman@billyJr:~$ ls -l /etc/init.d/vbox* -rwxr-xr-x 1 root root 6796 Mar 26 2014 /etc/init.d/vboxautostart-service -rwxr-xr-x 1 root root 10140 Mar 26 2014 /etc/init.d/vboxballoonctrl-service -rwxr-xr-x 1 root root 12680 Mar 26 2014 /etc/init.d/vboxdrv -rwxr-xr-x 1 root root 9917 Mar 26 2014 /etc/init.d/vboxweb-service @billyJr:~$ sudo rm /etc/init.d/vbox* Re-installation via synaptic of virtualbox and the associated dependencies worked without further issue. -- 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.
