Hi,
I have updated my elasticstack from version 7.17 to 8.0 recenly. All of my 3 Elasticsearch nodes and 2 logstash nodes are working fine. But whenever I am trying to upgrade to Kibana version 8.0 it is thowing below error.

You need to remove `xpack.canvas` from `kibana.yml` file. Probably you disabled it some time ago. Only a few plugins can be disabled starting from `v8.0`

Thank you for your reply. So I have hashed these lines which I am not using. Below is my xpack configuration.
> #xpack.monitoring.enabled: true
> #xpack.graph.enabled: false
> #xpack.ml.enabled: false
> xpack.security.enabled: true
> #xpack.watcher.enabled: false
> xpack.reporting.enabled: true
> xpack.spaces.enabled: true
> #xpack.canvas.enabled: true
> xpack.encryptedSavedObjects.encryptionKey: VALUE
> xpack.reporting.encryptionKey: VALUE
> xpack.security.encryptionKey: VALUE
> xpack:
> monitoring:
> enabled: true
> min\_interval\_seconds: 10
> monitoring.kibana.collection.enabled: false
But now below error is occurring. I am using SSL and TLS in elasticsearch, but not in Kibana. So is this the issue here?

Hi [Mikhail\_Shustov](https://discuss.elastic.co/u/Mikhail_Shustov),
Can you please check my previous comment and let me know what am I doing wrong?
> My error is "message":"[config validation of [xpack.security].enabled]: definition for this key is missing"
As xpack.security is mandatory what to do to remediate this?

Solved this by disabling xpack.security.enabled, xpack.reporting.enabled & xpack.spaces.enabled. As mentioned in document these setting are causing the problem.
