Question 1:
/opt/TurboVNC/bin/vncserver will create the ~/.vnc directory if it doesn't exist, and if /opt/TurboVNC/bin/vncserver creates ~/.vnc, then the directory will have the correct ownership and permissions for your user account. However, apparently you did something that caused ~/.vnc to be created with incorrect ownership or permissions. ~/.vnc should be owned by your user account and should have mode 700 (u+rwx,g-rwx,o-rwx).
Question 2:
I need to understand what you mean by "using root correctly for the first connection." Normally, it should never be necessary to run TurboVNC with root credentials, and doing so it not advised. What exactly are you trying to do?

The folder permissions are sufficient：

I used root because of Question 1. Currently, I am using the following command to restore normal operation,
apt-get -f install ubuntu-desktop
but I still need the root user to connect

The permissions on ~/.vnc must be exactly 700, not 777 as you showed above. That is to protect the VNC password from being read by other users.

As far as the XDG error, I'm not sure what you did to change the permissions of your XDG runtime directory, but you need to change them back. That is not a TurboVNC issue.
