Ok the problem was the vboxdrv.
While virtualbox was removed,
the vboxdrv was supplied by the virtualbox-dkms package (which was not removed).

Therefore removing manually virtualbox (again) and virtualbox-dkms (explicitly) removes everything.
Then reinstalling virtualbox solved the problem.

It turned out that it was more complicating than the above.

I had to use the update-rc.d to disable and remove any vbox* and virtualbox under /etc/init.d.

But this didn't solve the problem either. I had to manually move these files outside the /etc/init.d (this is equivalent to deleting them but I was not sure).

After that installing virtualbox worked.

the problem is the residual configuration of the virtualbox provided by oracle
rc virtualbox-4.2 4.2.16-86992~Ubuntu~precise amd64 Oracle VM VirtualBox

just remove it works
