# lsb\_release Utility Missing Resulting in Node to be in a Failed State

## Problem

Node is seen to be in a failed state from the management plane perspective.

{% tabs %}
{% tab title="None" %}

```none
abcdefgh-910f-080d-b36b-sf70929bacbc |  test.platform9.net  |  cni0:10.50.92.1 | True | failed  |  pf9-kube |
```

{% endtab %}
{% endtabs %}

On the node, the *pf9-nodeletd* service is in a dead state.

{% tabs %}
{% tab title="None" %}

```none
pf9@test:/var/log/pf9$ systemctl status pf9-nodeletd* pf9-nodeletd.service - Platform9 Kubernetes Management Agent Service  Loaded: loaded (/lib/systemd/system/pf9-nodeletd.service; disabled; vendor preset: enabled)  Active: failed (Result: exit-code) since Thu 2020-12-24 05:16:29 PST; 5 days ago  Process: 32556 ExecStart=/bin/bash -c /opt/pf9/nodelet/nodeletd >> /var/log/pf9/nodelet.log 2>&1 (code=exited, status=2) Main PID: 32556 (code=exited, status=2)
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Managed Kubernetes - All Versions

## Cause

Based on the Kube logs from when the service was last active, we can observe that it was failing to run the PMK stack scripts as it could not find the *lsb\_release* utility.

{% tabs %}
{% tab title="None" %}

```none
pf9@test:/var/log/pf9/kube$ less kube.logs[2020-12-22 11:52:16] os_ubuntu.sh: line 3: lsb_release: command not found--- /opt/pf9/pf9-kube/worker_scripts/020-gen_certs.sh start at 2020-12-22 11:52:16 ---[2020-12-22 11:52:16] os_ubuntu.sh: line 3: lsb_release: command not found--- status at 2020-12-22 12:01:24 ---[2020-12-22 12:01:24] os_ubuntu.sh: line 3: lsb_release: command not found--- status at 2020-12-22 19:02:57 ---
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="None" %}

```none
pf9@test:~$ which lsb_release
pf9@test:~$
```

{% endtab %}
{% endtabs %}

## Resolution

1. Install the missing utility.

{% tabs %}
{% tab title="None" %}

```none
pf9@test:~$ sudo apt-get install lsb-core
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="None" %}

```none
pf9@test:~$ which lsb_release
/usr/bin/lsb_release
```

{% endtab %}
{% endtabs %}

2. Restart the *pf9-hostagent* service.

{% tabs %}
{% tab title="None" %}

```none
pf9@test:~$ sudo systemctl restart pf9-hostagent
```

{% endtab %}
{% endtabs %}

3. Post restart of the *pf9-hostagent* service, the *pf9-nodeletd* service should start back up along with the rest of the PMK stack, and the node will then be reported to be in a healthy state to the management plane.

{% tabs %}
{% tab title="None" %}

```none
abcdefgh-910f-080d-b36b-sf70929bacbc | test.platform9.net | cni0:10.50.92.1 | True | ok | pf9-kube |
```

{% endtab %}
{% endtabs %}
