Chapter 2. Installing the command-line assistant powered by RHEL Lightspeed

The command-line assistant powered by RHEL Lightspeed is an optional tool available through the official RHEL 9 repositories.

Before you can start using the command-line assistant powered by RHEL Lightspeed, you must install it through the official RHEL repositories. The command-line assistant is supported in the following architectures:

  • AMD and Intel 64-bit (x86_64)
  • ARM64 (aarch64)
  • IBM Z (s390x)
  • IBM POWER systems (ppc64)

To access the command-line assistant powered by RHEL Lightspeed, install it by using RHEL repositories. Do not use pip install command-line-assistant because Red Hat does not support this installation option.

Prerequisites

Procedure

  • On your RHEL system, run the following command: 

    $ sudo dnf install command-line-assistant

Verification

  • Verify that the installation works by running the command-line assistant. For example: 

    $ c "How to install python?"

    The output looks similar to the following example: 

    +*+ Asking Red Hat Lightspeed

To install python....

  • Disable the color output in the command-line assistant. For example: 

    $ NO_COLOR=1 c “How to install python?"

You can install the command-line assistant powered by RHEL Lightspeed to your host registered to Red Hat Satellite. For that, update the command-line assistant endpoint, so that the RHEL system registered to Satellite can proxy command-line assistant by using the Satellite Server.

Prerequisites

  • Your system is registered with Red Hat Lightspeed for Red Hat Enterprise Linux.
  • You are using the command-line assistant on a host registered to a Satellite 6.17+ server or later versions.
  • The Satellite Server must be connected to the internet.
  • You have enabled the AppStream repository on the host to be able to install command-line assistant.

Procedure

  1. Install command-line assistant powered by RHEL Lightspeed on your registered host. 

    $ sudo dnf install command-line-assistant
  2. Locate and open the /etc/xdg/command-line-assistant/config.toml file.

  3. In the config.toml file, replace the endpoint configuration option to point to your Satellite or Capsule hostname, for example: 

    #The endpoint points to an API server.
endpoint = "https://satellite.example.server.com/api/lightspeed/v1"
  4. Save the changes in the config.toml file.

  5. Restart command-line assistant daemon (clad) for the changes to be effective:: 

    $ sudo systemctl restart clad

Troubleshooting

If the command-line assistant cannot trust the Red Hat Satellite certificate authority (CA), it cannot establish a secure connection to the Satellite Server. As a result, the assistant does not function. To work around this problem:

  1. Copy the Satellite CA certificate to the system truststore: 

    $ sudo cp /etc/rhsm/ca/katello* /etc/pki/ca-trust/source/anchors/

  2. Update the CA trust database: 

    $ sudo update-ca-trust
