@K. Deniz Ogut: To fix the problem do either
dpkg-reconfigure resolvconf
and elect to create the symbolic link at /etc/resolv.conf, or do
sudo ln -nsf ../run/resolvconf/resolv.conf /etc/resolv.conf sudo /sbin/resolvconf --enable-updates
Then reboot. If you don't want to reboot then, in each case with the appropriate means: stop local nameservers; deconfigure all network interfaces; configure network interfaces; start local nameservers.
