Reinstalling Kaspersky Next XDR Expert after a failed installation

If the installation of Kaspersky Next XDR Expert failed, you can restart the installation. Installation failure may occur during installation of Bootstrap or installation of Kaspersky Next XDR Expert components. The steps needed to reinstall Kaspersky Next XDR Expert depends on whether the Kubernetes cluster was deployed when the installation error occurred.

To determine the stage at which the installation failed,

Run the following command to view the list of all installed Kaspersky Next XDR Expert components:

./kdt state

If the Bootstrap installation error occurs, KDT displays a message that Bootstrap is not installed. In this case, you have to manually uninstall the directories created during the deployment.

If Bootstrap is installed successfully, it will have the Success status in the command output. This means that a Kaspersky Next XDR Expert components installation error occurred. In this case, you have to reinstall the components that were not installed correctly or reinstall the entire solution. In the command output, such components have the Failed status.

Reinstalling Kaspersky Next XDR Expert if Bootstrap is not installed

To restart the Kaspersky Next XDR Expert installation:

1. Go to the directory with the KDT utility, and view the installation logs of the Bootstrap component.

   If a failure occurred during the Bootstrap installation stage, this will be reflected in the log. In this case, Bootstrap has not been installed and the Kubernetes cluster has not been created.

2. Manually uninstall the directories created during the deployment.
   1. On the administrator host, go to the .kdt directory, and then remove the cluster.config file.

   2. Remove the contents of the following directories:

      • Required directories:

        • /etc/k0s/
        • /var/lib/k0s/
        • /usr/libexec/k0s/
        • /usr/local/bin/ (remove only the k0s file)

      • Optional directories:

        • /var/lib/containerd/
        • /var/cache/k0s/
        • /var/cache/kubelet/
        • /var/cache/containerd/

        You can remove the /var/lib/containerd/ and /var/cache/containerd/ directories if the containerd service is used only for the function of Kaspersky Next XDR Expert. Otherwise, data contained in the /var/lib/containerd/ and /var/cache/containerd/ directories may be lost.

        The contents of the /var/cache/k0s/, /var/cache/kubelet/, and /var/cache/containerd/ directories are automatically removed after you restart the target host. You do not have to clear these folders manually.

   3. Restart all target hosts.
3. Restart the installation of Kaspersky Next XDR Expert.
