Ubuntu Authentication Error
I've installed VNC Server on Ubuntu 22.04 Jammy. When I try to open VNC server I get a prompt asking for my password: "Authentication is needed to run '/etc/VNC/vncservice' as the super user." Even after I input my password nothing happens. I have checked systemctl and the vnc-server service is running. Any advice would be appreciated.
Same problem here.
Same here, I run Ubuntu 22.04, I have disabled Wayland on /etc/gdm3/custom.conf and the services vncserver-x11-serviced.service & vncserver-virtuald.service shows as active and running.
I think is a general issue with Ubuntu. When I type 'sudo vncserver' it says it's not finding license keys.
I installed vncserver following this:
Same as me, I can't open the GUI on Ubuntu 22.04.

The vncserver command starts Virtual Mode, which is an Enterprise only feature. Other subscriptions need to use Service Mode which is started by running:
sudo systemctl enable vncserver-x11-serviced --now
For those that cannot open the GUI, please double check you have disabled Wayland as shown here: https://help.realvnc.com/hc/en-us/articles/4417193011857
and rebooted the VNC Server computer afterwards.
If the VNC Server GUI still doesn't appear after selecting it in Applications, try manually opening it by running the command:
sudo vncserver-x11 -service -showexistingstatus
