2023-02-05 18:34:41 [2023-02-05T17:34:41.501+00:00][ERROR][plugins.apm] RegistryResponseError: '404 Not Found' error response from package registry at https://epr.elastic.co/epr/apm/apm-8.6.1.zip

When checking the registry is seem like the latest version is 8.4.2

$ curl -s https://epr.elastic.co/search?package=apm | jq .[].version
"8.4.2"

I was expecting an server running on port 8200, but I might have misunderstood how it is suppose to work with the integration. and the legacy apm-server will be deprecated
Please advice,

Same problem, installed 8.6.1 on ubuntu.
https://epr.elastic.co/epr/apm/apm-8.6.1.zip is missing.
Tried to switch to air-gapped architecture with self managed package registry. But the apm/apm-8.6.1.zip is missing as well.

There is open issue with a workaraond : Kibana APM Settings Schema page returns 500 errors. · Issue #149342 · elastic/kibana · GitHub
The workaround is to manually install the APM integration. From Dev tools, as superuser, run:

POST kbn:/api/fleet/epm/packages/apm/<version>
{
  "force": true
}
