This is how to solve he problem

sudo apt-get install libvncclient0

for some reason I still need to use sudo in order to use vnc with remmina

sudo remmina

this solves the problem!

[Uldis Kalniņš (ulcha)]

If you started remmina with sudo, then remmina creates config files with root ownership. You can chown permissions back from root to your user, then use without sudo.

This solution does not work on Ubuntu 14.04 anymore.

[Saurabh Gupta (bhaismachine)]

Removing and reinstalling libvncserver0 fixed this issue for me.

sudo apt-get remove libvncserver0
sudo apt-get install libvncserver0

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 ) .

[ConceptRat (conceptrat)]

The library "libvncclient" was split out of the package "libvncserver0" at version "libvncserver_0.9.9+dfsg-5ubuntu1". The package "remmina-plugin-vnc" that you, and I (Trusty), are using was built on the previous version of "libvncserver0" that being "libvncserver_0.9.9+dfsg-1ubuntu1.3" (last one before the split). This version included "libvncclient.so.0.0.0" and linked to from "libvncclient.so.0".

If you wanted to use a later version of "libvncserver", like say "libvncserver0_0.9.9+dfsg-6ubuntu1.1" then you'll also need to install the package "libvncclient0_0.9.9+dfsg-6ubuntu1.1".
