How to Install Syncthing on Ubuntu 24.04

You can install Syncthing on Ubuntu 24.04 to automatically sync files and folders across your devices.

Syncthing is a free, open-source application that creates a peer-to-peer file synchronization network, meaning it transfers data directly between your computers without relying on a central server. This ensures your data remains private.

With Syncthing, you get secure, encrypted file transfers between your machines. You can select which folders to sync and even control bandwidth usage, providing a flexible and private way to keep your files consistent.

⚡ Quick Answer

Install Syncthing by opening your terminal and running “sudo apt update” followed by “sudo apt install syncthing”. Enable the service to start automatically with “systemctl –user enable syncthing”. Access the web interface at http://127.0.0.1:8384 to configure your sync settings.

Install Syncthing

Installing Syncthing on Ubuntu 24.04 uses terminal commands. These commands place the Syncthing software on your Ubuntu 24.04 system. The installation prepares Syncthing to start automatically when you log into your Ubuntu 24.04 system, allowing immediate use.

sudo apt update
sudo apt install syncthing

⚠️Warning
Syncthing automatically starts on Ubuntu 24.04 when a user logs in. To set up Syncthing's automatic startup, run the command `sudo systemctl enable syncthing@$USER.service`. This command ensures Syncthing synchronizes files without manual intervention each time a user starts a session.

systemctl –user enable syncthing

You can start or stop the Syncthing service whenever you need with these commands:

systemctl –user start syncthing
systemctl –user stop syncthing

Configure Syncthing

⚠️Warning
Syncthing's web interface needs a secure login to protect file syncing. Users create this Syncthing login by opening Syncthing's web address in a browser and accessing settings. Within Syncthing's settings, users select a username and password for the Syncthing portal. This action ensures only authorized people can use Syncthing's file syncing functions.
  1. Open your web browser and go to http://127.0.0.1:8384.
  2. Navigate to the Settings menu in the top right corner.
  3. Click on the GUI tab.
  4. Enter a unique username and a strong, secure password in the provided fields.
  5. Click Save.

The interface will refresh and prompt you to log in with your new credentials.

Log in to the Syncthing portal

You can log in to the Syncthing portal using your web browser by going to a specific address. If you have trouble accessing it, you might need to check if the Syncthing service is running and confirm you’ve set up your username and password correctly in the GUI settings.

systemctl –user status syncthing

Open a browser and go to http://127.0.0.1:8384. Navigate to the Settings menu (top right corner) and click the GUI tab. Enter a unique username and a strong, secure password. Then, click Save.

https://your-ip-address:8384

Enter the username and password you just created to log in.

Click “Add Remote Device” on the remote host and enter the connection ID you copied from the other host. Return to the original host and confirm the request to connect.

Using GUI Wrappers

If you prefer not to use a web browser, you can install a GUI wrapper. These tools sit in your desktop taskbar and make managing your sync status much easier. Look for “Syncthing GTK” or “SyncTrayzor” in your software center to simplify your daily management.

Conclusion

Syncthing provides a flexible and private method to synchronize files across personal devices. Syncthing is a free, open-source tool that directly connects devices, allowing users to select folders for real-time syncing without a central server.
