Also for some reason "sudo apt-get install --reinstall libvncserver0" did not work for me because it said the package wasn't found. On removing libvncserver0 first, and then reloading the synaptic I realized that synaptic showed a slight version difference .
(now showed version libvncserver0_0.9.9+dfsg-1ubuntu1.1_amd64.deb instead of previously installed version libvncserver0_0.9.9+dfsg-6ubuntu1.1_amd64.deb ) .
Removing and reinstalling libvncserver0 fixed this issue for me.
sudo apt-get remove libvncserver0
sudo apt-get install libvncserver0
