Install OS Updates

Before deploying the FluxNode software, it’s critical to bring your operating system fully up to date with the latest security patches and package improvements.

💡 Note: For the purpose of this guide, we’ll walk through the process using a VPS server rental scenario while configuring a Cumulus FluxNode. If you’re running FluxNode from home, steps may differ slightly. In this example, we’ll be using PuTTY as our SSH client to connect to the server.

Why Update?​

  • Security: Protects against known vulnerabilities.
  • Stability: Ensures compatibility with recent libraries and dependencies.
  • Performance: May include kernel and driver improvements.

Step-by-Step​

1. Connect via SSH​

  • Ensure you’re logged in as root (or an admin user with sudo privileges).

2. Update Package Lists & Update​

  • Run the following command:
sudo apt update && sudo apt dist-upgrade -y
  • apt update refreshes the package index.
  • apt dist-upgrade installs all available updates and handles any package dependencies.

3. Wait for Completion​

  • The system will download and install updates.
  • This may take several minutes, depending on your server’s resources and network speed.

4. Verify​

  • Once finished, you’ll return to the prompt:
root@servername:~$
  • Optionally, reboot to apply kernel updates:
sudo reboot

Once the OS is updated, proceed to Networking Configuration if you’re using a home-based server, or to Install FluxNode Software if you’re using a VPS.
