I can use sudo vncserver-x11-serviced & to start a VNC Server as a daemon.

I need to execute this command whenever I boot or reboot Raspberry Pi.

From https://www.realvnc.com/en/connect/docs/man/vncserver-x11-serviced.html, I learned that sudo update-rc.d vncserver-x11-serviced defaults is the command.

However, vncserver-x11-serviced is in /usr/bin, so I made a symbolic link in /etc/init.d with sudo ln -s /usr/bin/vncserver-x11-serviced /init.d/vncserver-x11-serviced

Then, I executed sudo update-rc.d vncserver-x11-serviced defaults as is written in the webpage.

However, when I try to access the Raspberry Pi RealVNC server using RealVNC Viewer, I have the error message.

What might be wrong?

    Which OS/Distro do you use? Raspbian uses systemd, so you may be using the wrong command. The correct one for Raspbian starts with sudo systemctl enable ... as listed on the RealVNC web page you link to.

  • @Dirk: I use Raspibian, I thought it's Debian based (from the book Raspberry Pi Cookbook). So, I tried update-rc.d.

  • Debian also uses systemd (starting with Jessie). You're apparently using outdated information...

  • If you are using Raspbian just enable in raspi-config

  • You should not use scripts in /etc/init.d/ anymore: raspberrypi.stackexchange.com/a/101852/79866

sudo systemctl start vncserver-x11-serviced.service solved this issue. I downloaded VNCReal server without knowing Raspberry Pi already has it. Reinstallation of Raspibian and execution of the systemctl solved this issue.

I found that sudo raspi-config has `interfacing options' to turn on VNC too. https://www.realvnc.com/en/connect/docs/raspberry-pi.html
