Install Syncthing on Ubuntu 16.04 via Official Deb Repository

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

sudo apt-get install curl 

curl -s https://syncthing.net/release-key.txt | sudo apt-key add -

-s option enables silent mode.

If you see OK in the terminal, that means the GPG key is successfully imported. Then add official Syncthing deb repository with the following command.

echo "deb http://apt.syncthing.net/ 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 as a Systemd Service

The official Syncthing deb package ships with the needed systemd service file. Under /lib/systemd/system/ directory, you will find a syncthing@.service file. 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

The above command will create a symbolic link that points to the syncthing@.service file.

Created symlink from /etc/systemd/system/multi-user.target.wants/syncthing@linuxbabe.service to /lib/systemd/system/syncthing@.service.

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

sudo systemctl start syncthing@username.service

Check status

systemctl status syncthing@username.service

Output:
