If your Ubuntu 16.04 system doesn’t have Syncthing, here’s how to install it via the official APT repository.

Use curl to download the Syncthing GPG key then import the key to Ubuntu system with apt-key.

sudo apt install curl

curl -s | sudo apt-key add -

Then add official Syncthing deb repository with the following command.

echo "deb syncthing release" | sudo tee /etc/apt/sources.list.d/syncthing.list

Update local package index and install Syncthing on Ubuntu 16.04 LTS.

sudo apt-get update

sudo apt-get install syncthing

This deb repository also works on Debian or other Debian/Ubuntu-based Linux distros such as Linux Mint, Elementary OS.

Set Up Syncthing Systemd Service

The official Syncthing deb package comes with the needed systemd service file. Under /lib/systemd/system/ directory, you will find a [email protected] file. You can enable Syncthing to auto start when Ubuntu is booted up by running the below command. Replace username with your actual username.

sudo systemctl enable syncthing@username.service

Now we can start the Syncthing Systemd service with the following command.

sudo systemctl start syncthing@username.service

Let’s check its status.

systemctl status syncthing@username.service

  • And should we do for SyncThing to start at system boot (not only when the user log in)?

    Creating a /etc/systemd/syncthing.conf file with the command “sudo systemctl start syncthing@[username].service”?

      The command

      sudo systemctl enable [email protected]

      creates a symlink under /etc/systemd/system/ directory, which means syncthing will be started at system boot.
