Upgrading elastic-agent on Ubuntu

Elastic Security

Hi,

What is the best way of upgrading elastic-agent running on Ubuntu Linux when using a Fleet server?

The Fleet console in Kibana does not give an option to upgrade these agents. I can upgrade elastic-agent running on Windows via this method.

When I try and upgrade using elastic-agent itself on the command line I receive the below:

root@gremlin2:~# elastic-agent upgrade 7.16.2 The upgrade process of Elastic Agent is currently EXPERIMENTAL and should not be used in production Error: Failed trigger upgrade of daemon: cannot be upgraded; perform upgrading using Fleet For help, please see our troubleshooting guide at https://www.elastic.co/guide/e n/fleet/7.15/fleet-troubleshooting.html

I can upgrade the elastic-agent package manually using apt but that breaks the enrollment and is fiddly to fix.

What is the correct way to upgrade elastic-agents in this instance?

I'm running Ubuntu 20.04.03, elastic-agent 7.15.2, kibana/Elasticsearch 7.16.2.

cheers,

Michael

I think u can only upgrade if u install via the tar.gz method, not of installed via package manager or docker.

You are correct, fleet managed upgrades are only supported when installed through the .tar.gz files
