how to install realvnc server Debian 13

Installing RealVNC Server on Debian 13 allows you to control your system remotely with a fast, secure, and user-friendly VNC connection. 

Step 1: Update Your System

Before installing any software, make sure your Debian 13 system is up to date to prevent errors during installation.

sudo apt update && sudo apt upgrade -y

Step 2: Download the RealVNC Server Package

To install RealVNC on Debian 13, you first need to download the official .deb package directly from RealVNC’s trusted source to ensure security and compatibility with your system.

wget https://downloads.realvnc.com/download/file/vnc.files/VNC-Server.deb

Step 3: Install RealVNC Server

After downloading the package, install RealVNC Server using the Debian package manager to automatically set up all necessary files and dependencies for remote desktop access.

sudo dpkg -i VNC-Server.deb
sudo apt --fix-broken install -y

Step 4: Enable and Start the RealVNC Service

Once the installation is complete, you need to enable and start the RealVNC service so it runs automatically on boot and allows remote connections to your Debian 13 system.

sudo systemctl enable vncserver-x11-serviced  
sudo systemctl start vncserver-x11-serviced

Step 5: Allow VNC Through the Firewall

To ensure remote connections work properly, you must allow VNC traffic through the firewall so that external devices can securely connect to your Debian 13 system.

sudo ufw allow 5900/tcp  
sudo ufw reload

Step 6: Connect to RealVNC Server

After setting up the service and firewall, you can now connect to your Debian 13 system from any device using the RealVNC Viewer application.
