Hello All,
I am fairly new to entire elk stack and right now trying to setup a home lab. I am facing a weird issue while adding a fleet server.
I am using the official guide to install and whenever i am doing:
sudo ./elastic-agent install
--fleet server-es=https://\*\*\*\*\*\*\*\*\*\*\*\* and further cmd.
it gives me error:
bash: ./elastic-agent:cannot execute binary file : Exec format error.
can anyone advise what could be causing it?
I am running both kibana 8._._ and ELK 8._._ on centOS 9.

Hi Tirath,
It sounds like you are using a binary that is not valid for your OS/Architecture.
Can you check in the downloads and try the binary for your architecture? [Elastic Agent 8.9.0 | Elastic](https://www.elastic.co/downloads/past-releases/elastic-agent-8-9-0)
`uname -a` will tell you what architecture you have on Linux so you can pick the right binary.
