Installing RealVNC Server on Ubuntu 25.10 allows you to access your desktop remotely with a secure and user-friendly interface.

Step 1: Update Your System

Before installing RealVNC, make sure your system packages are up to date to prevent conflicts and ensure stability during installation.

sudo apt update && sudo apt upgrade -y

Step 2: Download RealVNC Server Package

Next, download the latest RealVNC Server .deb package directly from the official RealVNC repository using wget.

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

Step 3: Install RealVNC Server

After downloading the package, you can easily install RealVNC Server using the Debian package manager to set up all necessary components and dependencies for remote access.

sudo dpkg -i VNC-Server.deb

If you encounter dependency issues, fix them with:

sudo apt --fix-broken install -y

 

Step 4: Enable and Start RealVNC Service

Once RealVNC is installed, you need to enable and start its service to ensure it runs automatically and allows remote connections right after system boot.

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

You can verify its status using:

sudo systemctl status vncserver-x11-serviced

Step 5: Allow VNC Through Firewall

To make sure you can connect to your Ubuntu system remotely, you must allow VNC traffic through the system firewall for seamless and secure access.

sudo ufw allow 5900/tcp
sudo ufw reload

Step 6: Access RealVNC Server

Once everything is configured, you can connect to your Ubuntu desktop remotely using the RealVNC Viewer. Use your system’s IP address followed by :5900 in the viewer to start the connection.

Step 7: Secure Your VNC Server

For better security, it’s recommended to set a strong password and enable encryption through the RealVNC Server settings. You can access these settings from the RealVNC Server UI or command line.
