**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.

Hi Pablo,
We’ve opened an issue on GitHub OpenSearch Documentation.
>
>
> Hi OpenSearch team,
> Could you please clarify whether \*\*Debian 13\*\* and \*\*Ubuntu …26.04 LTS\*\* are officially supported operating systems for OpenSearch and OpenSearch Dashboards?
>
> The current documentation states that OpenSearch is compatible with Debian-based Linux distributions that use systemd, such as Ubuntu LTS. However, the OS compatibility matrix only lists the operating systems currently tested, and I can currently see Ubuntu 24.04 listed, but not Debian 13 or Ubuntu 26.04 LTS.
>
> Could you confirm whether:
> \- Debian 13 is officially supported;
> \- Ubuntu 26.04 LTS is officially supported or planned for support;
> \- the compatibility matrix can be updated to include them if they are supported?
>
> This would help users make informed decisions for production deployments and OS lifecycle planning.
>
> Thanks in advance.

Thanks
