Hi, I'm trying to add a new fleet server in kibana. When I try to install the Fleet Server Agent on a centralized host, I'm getting errors after I input the following code:

```auto
curl -L -O https://artifacts.elastic.co/downloads/beats/elastic-agent/elastic-agent-8.6.2-darwin-x86_64.tar.gz
tar xzvf elastic-agent-8.6.2-darwin-x86_64.tar.gz
cd elastic-agent-8.6.2-darwin-x86_64
sudo ./elastic-agent install \
  --fleet-server-es=https://192.168.0.8:9200 \
  --fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE2NzcyMDA0MjM2ODU6a09xWXhHMkFUaVdKR3hISWYxdG12dw \
  --fleet-server-policy=91199d40-b3de-11ed-8b81-f777bcc92e8c \
  --fleet-server-es-ca-trusted-fingerprint=046f5cf06bb5179a1f6afd0778006d0b556bdd67c56aed6cc3f2872a336cc044

```

The error I get is this:

```auto

I'm trying to do this on my local machine - an m1 macbook air.

Please advise.

Thanks!

Stephen
