Why does the host registration script fail?

{: #host-registration-script-fails}

When you SSH into your own infrastructure machine that you want to attach as a {{site.data.keyword.satelliteshort}} host and run the host registration script, you see a message similar to the following example. {: tsSymptoms}

No package rh-python36 available.
Error: Nothing to do

{: screen}

Your machine does not meet the minimum requirements to become a {{site.data.keyword.satelliteshort}} host. In particular, you must have the following packages installed on your RHEL 7 or 8 machine. {: tsCauses}

For RHEL 7

Repository 'rhel-server-rhscl-7-rpms' is enabled for this system.
Repository 'rhel-7-server-optional-rpms' is enabled for this system.
Repository 'rhel-7-server-rh-common-rpms' is enabled for this system.
Repository 'rhel-7-server-supplementary-rpms' is enabled for this system.
Repository 'rhel-7-server-extras-rpms' is enabled for this system.

{: screen}

For RHEL 8

Repository 'rhel-8-for-x86_64-appstream-rpms' is enabled for this system.
Repository 'rhel-8-for-x86_64-baseos-rpms' is enabled for this system.

To resolve this issue, follow these steps. {: tsResolve}

  1. Add the required packages to your machine. For example, in {{site.data.keyword.IBM_notm}} Cloud infrastructure you can run the following commands to add the required packages. For cloud provider-specific configurations, see Cloud infrastructure providers.

    1. Refresh the {{site.data.keyword.redhat_notm}} packages on your machine.

      subscription-manager refresh

      {: pre}

      If you see an error such as Network error, unable to connect to server. Please see /var/log/rhsm/rhsm.log for more information., check the security group and other network settings for your machine to make sure that you have connectivity to the internet. {: tip}

    2. Enable the package repositories on your machine. For example, enable RHEL 8 package requirements.

      subscription-manager repos --enable rhel-8-for-x86_64-appstream-rpms
subscription-manager repos --enable rhel-8-for-x86_64-baseos-rpms

      {: pre}

  2. Make sure that your machine meets the other host minimum requirements, such as minimum CPU and memory sizes.

  3. Run the registration script on your machine again.
