Step 1 add Syncthing repo to apt sources

Syncthing isn’t available to install using the default repo. So the first step is adding syncthing repo to our apt sources so we can install it on our computer. We need to open up a terminal and run the following command.

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

Step 2 Installing curl

We need to make sure we have curl installed, so we can install the syncthing PGP key. All we need to do is the following command.

sudo apt install curl

If it is already installed you will get this message

If you need to install it your screen will look like this one. does not exist

Step 3 – Add Syncthing’s PGP Keys

The next step we need to do Is add the synching repo PGP key to our apt keys. Without this apt will not trust synching repo and will not install syncthing.

curl -s | sudo apt-key add -

You should see the following if you added it correctly.

Step 4 – Update apt’s database

We now need to update download package information from synching and your other sources set up on your computer. We do that by running sudo apt update.

sudo apt update

Step 5 – Installing Syncthing

We finally get to install Syncthing on Linux. We just need to type the command below and press enter.

sudo apt install syncthing

Step 6 – Enable the Syncthing service

Now we got syncthing installed we need to enable syncthing to start at boot using the systemctl command. But make sure you replace username with your username in the following command. put please don’t use root it is a security issue.

sudo systemctl enable syncthing@username.service

Now, let’s start up syncthing up for the first time by running this command below. Make sure you change username to your username.

sudo systemctl start syncthing@username.service

sudo pico .config/syncthing/config.xml

Need to find It is under the . We need to change it from to

Then we need to restart the syncthing service by running this command. Make sure you change the username to your username again
