Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): OpenSearch 3.7

Describe the issue:

Hi everyone,
I’m new to OpenSearch and currently setting it up for the first time. I have a question regarding OS compatibility: is it possible to install and run OpenSearch on Ubuntu 26.04 instead of the officially supported Ubuntu 24.04?

The documentation lists 24.04 as the supported version, but before proceeding I’d like to know whether anyone has successfully installed and configured OpenSearch on Ubuntu 26.04, and whether there are known issues or compatibility problems.

Also, another question: has anyone installed OpenSearch on Debian 13? If so, did you encounter any issues?

Thanks in advance for any insights.

@RobertoManconi How do you deploy the cluster? Is it Docker, service or binary?

Hi Pablo,

as service using APT repository and systemd.

Thanks,

Roberto

@RobertoManconi I’ve tested both Debian 13 and Ubuntu 26.04.
I’ve ingested around 500k documents. Node was stable. Also, haven’t noticed any unusual errors during the startup.
I’ve also tested a multinode Docker setup on both distros and had no issues.

This was a simple test, and I can’t state how other plugins would behave. How do you want to use that cluster?

Regarding documentation and supported versions, you can raise a GitHub issue in the OpenSearch documentation repo.
If you do so, please share the link here for traceability.
