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.
