# Install Standard on Linux

> This is a step-by-step guide to installing the Standard System on Ubuntu or Debian Linux using the APT package manager, including license activation.

If you're running a relay or running the Standard System on or as a server, Linux is the best choice. You can download the Linux installer from [standardcomputers.net/downloads](https://standardcomputers.net/downloads) and run it directly, or follow the CLI steps below to install Standard via the APT package manager — the recommended approach for server and relay deployments.

<Note>
  Linux (Ubuntu or Debian) is the recommended platform for running Standard as a server or relay. Other distributions are not officially supported at this time.

<Steps>
  <Step title="Install the signing key">
    Add the Standard Computers GPG signing key to your system's trusted keyring so APT can verify packages from the Standard repository.

    ```bash theme={null}
    curl -fsSL https://standardcomputers.net/downloads/standardcomputers.gpg \
      | sudo gpg --dearmor -o /usr/share/keyrings/standardcomputers.gpg
    ```
  </Step>

  <Step title="Add the repository">
    Register the Standard Computers APT repository as a package source. This allows `apt update` and `apt install` to locate the `standard` package.

    ```bash theme={null}
    echo "deb [signed-by=/usr/share/keyrings/standardcomputers.gpg] https://standardcomputers.net/repo stable main" \
      | sudo tee /etc/apt/sources.list.d/standardcomputers.list
    ```
  </Step>

  <Step title="Install Standard">
    Refresh your package index and install the Standard System package.

    ```bash theme={null}
    sudo apt update && sudo apt install standard
    ```
  </Step>

  <Step title="Activate your license">
    Run `standard` to launch the CLI. On first launch, the system will prompt you to enter your activation details. **You do not need to enter account info if you are not using the public relay!**

    * **License key** — your unique product license
    * **Username** — the username you registered with
    * **User ID** — your Standard account identifier
    * **Device Serial** — the serial number assigned to this device
    * **Device Chit Token** — the authentication token for this device

    Once activation completes, your Standard System is ready to use.
