Performing Offline Updates

You can perform an update by using an offline ISO file under the following conditions:

  • When there is no internet access and you are unable to register the appliance.

  • When you prefer not to download the latest release available in the appliance download repository, but an earlier release. For more information, see Product Support Lifecycle.

  • When the current version that you are running is incompatible with the latest version, download a version that is compatible and then upgrade it to the latest version. For more information, see Product Support Lifecycle.

While applying the patch, if you encounter registry/ repository issues, clear the registry and repository entries in your system.

To clean up the registration and repository details on the appliance:

  • Take a backup of the files before clearing the registry entries and create a backup directory. For example: mkdir /etc/zypp/backup

  • Copy the following registry files to the backup directory. For example:

    • cp /etc/zypp/credentials.d /etc/zypp/backup

    • cp /etc/zypp/repos.d/* /etc/zypp/backup

    • cp /etc/zypp/services.d/* /etc/zypp/backup

  • Delete the following registry files:

    rm -fr /etc/zypp/credentials.d

    rm -fr /etc/zypp/repos.d/*

    rm -fr /etc/zypp/services.d/*

To apply the patch:

  1. Download the patch to a directory. For example: <directoryname>/change_guardian_offline_appliance-<version>.iso

  2. Create a directory for mounting the CD using a command. For example: mkdir -p /opt/trial

  3. Mount the patch CD locally using a command. For example:

    mount <directoryname>/change_guardian_offline_appliance-<version>.iso /opt/trial

  4. Add the product and operating system repositories. For example:

    zypper ar -c -t plaindir "/opt/trial/product-repo" "<product repository>"

    zypper ar -c -t plaindir "/opt/trial/osupdate-repo" "<operating system repository>"

  5. (Optional) Confirm if the repos are added successfully using the command: zypper repos
