I'm running a standalone agent on an airgap Windows system using the zip deployment. I'm trying to upgrade from 8.19.0 to 8.19.15 as a test.
It appears that there is a way to use the elastic-agent.exe upgrade command with the --source-uri argument (docs say this argument accepts file://<file path>) to point to an Elastic Agent zip package to upgrade the agent and it appears to want to always look in "~\Elastic\Agent\data\elastic-agent-X.X.X-xxxxxx\downloads" no matter the path you give it.
I tried multiple paths (and slash variants) and even tried putting the zip file in the place it is looking for and it still fails claiming it can't find the zip package. Ironically after the command fails, it deletes the zip file I place in the downloads folder.
Am I doing this wrong? Is this supported?
