I have Ubuntu server (18.04) and I wanted to visualize it using VNC, I managed to install ubuntu-desktop and tigervncserver, but failed to visualize. I used several ways that I got from the internet but also failed. Then I tried to install lubuntu-desktop, but also failed. Here is my log:

I suppose there is somethig wrong with the encoding? When I connected it via VNC Viewer, it says that the connection will not be encrypted, and after inputing password, it just turns gray screen.

Looks like that there is no solutions for gnome, so I chose xfce4

 $ sudo apt update
    $ sudo apt install xfce4 xfce4-goodies
    $ sudo apt install tightvncserver
    $ vncserver
    $ vncserver -kill :1
    $ mv ~/.vnc/xstartup ~/.vnc/xstartup.bak
    $ nano ~/.vnc/xstartup
    (paste the follow being in the xstartup file and write out)

#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &

$ sudo chmod +x ~/.vnc/xstartup
$ vncserver
