Hi @yomofo2s, which repos are you using to get the packages from?

[fede843]

I came acros a similar issue. I started using Debian stable, but it turn out Otel is in mainline. Same for Ubuntu: https://nginx.org/en/linux_packages.html#Ubuntu

Hi @thresheek I am using Ubuntu jammy repo

@fede843 i recently noticed that nginx-module-otel is not public available in nginx image but in nginx-plus (which is a paid version). Correct me if I am wrong.

[fede843]

mmm I am not an expert, and I did not get to install it at the end. Gave up and came back to the otel cpp project.

Yet I can see http://nginx.org/packages/mainline/ubuntu/pool/nginx/n/nginx-module-otel/
Did you add the repo and update it?

[fede843]

and also by reading at https://docs.nginx.com/nginx/admin-guide/dynamic-modules/opentelemetry/
says

"the code of NGINX OpenTelemetry module is open source since [NGINX Open Source](https://nginx.org/) 1.25.2 and [NGINX Plus Release 30](https://docs.nginx.com/nginx/releases/#r30). The source code is available on [GitHub](https://github.com/nginxinc/nginx-otel)."

[yomofo2s]

@fede843 yes i add and updated the repo. I also used this repo https://nginx.org/en/linux_packages.html#instructions

[fede843]

docker run --name nginx_test_ubu --rm -it ubuntu:mantic

Thanks this works :)

Indeed, otel module is available since 1.25.3 in the nginx.org repositories. So mainline only for now.
