I have read those questions: Why can't I access a shared folder from within my Virtualbox machine? and Error: kernel headers not found. (But they are in place)
The second question equals mine, but the solutions there do not work.
I have a Kubuntu host with Lubuntu guest system. When I install the vbox guest additions the logfile states (as in the other questions):
