Part 2 – Software installation

This section will help you install all the necessary software for your node.

Install dependencies

Now let’s move on to the Pocket CLI installation.

At this point you should be logged in via SSH as the pocket user that we set up in a previous step. Before we install the Pocket software, we need to update the existing system packages and add a few dependencies.

Updating system packages

  1. Update the repository index with the following command:
    sudo apt update
  2. Update the distribution with the following command:
    sudo apt dist-upgrade -y

After the update completes, we’re ready to install the dependencies.

Installing dependencies

There are a handful of dependencies but installing them won’t take long. Also, some might already be installed. So if one of the dependencies exists, you can just move on to the next one.


sudo apt-get install git -y

build tools

sudo apt-get install build-essential -y


sudo apt-get install curl -y


sudo apt-get install file -y


sudo apt install nginx -y


sudo apt install certbot -y


sudo apt-get install python3-certbot-nginx -y


sudo apt install jq -y

Install Go

After installing the dependencies, there is one more dependency we’ll need to add, and that’s Go. Go (sometimes known as “Golang”) is the programming language that the Pocket software was written in.

We could install Go using apt, but we want to get the latest stable version which probably isn’t available by default in the apt repository. So, we’ll use the steps below to install Go.

  1. Make sure you’re in the pocket home directory.
    cd ~
  2. Find the latest version of Go from then download it with the following command. (Make sure to change the link below to point to the correct version of Go.)
  3. Extract the archive:
    sudo tar -xvf go1.19.2.linux-amd64.tar.gz
  4. Set permissions on the extracted files:
    sudo chown -R pocket ./go
  5. Add Go to the PATH:
    echo 'export PATH=$PATH:$HOME/go/bin' >> ~/.profile
  6. Set the GOPATH and GOBIN environment variables:
    echo 'export GOPATH=$HOME/go' >> ~/.profile
    echo 'export GOBIN=$HOME/go/bin' >> ~/.profile
  7. Reload your .profile:
    source ~/.profile
  8. Verify the installation:
    go version
    go version go1.19.2 linux/amd64

    Make sure the version number matches the version you downloaded. If the go version command doesn’t work, try logging out and logging back in.

  9. Verify the GOPATH and GOBIN variables are set correctly:
    go env

Install Pocket

After you can verify that you have the latest stable version of Go, we’re ready to install the Pocket software.

We’ll be downloading Pocket Core from GitHub and then compiling it with Go to get it fully installed.

To download and install Pocket Core, do the following:

  1. Create a project directory:

    sudo mkdir -p $GOPATH/src/
  2. Change to the project directory:

    cd $GOPATH/src/
  3. Clone the Pocket Core repository:

    sudo git clone
  4. Change to the code directory:

    cd pocket-core
  5. Checkout the latest version. You can find the latest tag by going to

    sudo git checkout tags/RC-0.9.2

    You may see a warning about being in a “detached HEAD” state. This is normal.

  6. Build project code:

    go build -o $GOPATH/bin/pocket $GOPATH/src/
  7. Test that the build succeeded:

    pocket version
    AppVersion: RC-0.9.2

That’s it for the software installation. Now let’s move on to the Pocket core configuration.
