Popup during boot up initializations: "VBoxClient: the VirtualBox kernel service is not running. Exiting" [duplicate]

Solution 1:

I had the same trouble. Because no virtualbox was installed, i typed on terminal as root " locate virtualbox" and I could see ' virtualbox-guest-utils' & 'virtualbox-guest-x11' VBox in '/etc/init.d. But the troubles remained, because there is another file to delete in /etc/X11/Xsession.d/98vboxadd-xclient. Only deleting it as root, I finally eliminate the message. I suppose that the truble is connected with deleting wine ochanging it in some way

Solution 2:

Solved this problem in Ubuntu 16.04, pay attention to the purge command which deletes configuration files

sudo apt --purge remove 'virtualbox-guest-*'

I've found it here
