Checking /var/log/fluent/fluentd.log might help you.

Ah, fluent-package is not supported on ubuntu 24.10.

[Watson1978]

You should need to follow the way in https://docs.fluentd.org/installation/install-by-gem

FYI)

Note

Step 1: Install from Apt Repository
NOTE: If your OS is not supported, consider gem installation instead.

https://docs.fluentd.org/installation/install-fluent-package/install-by-deb-fluent-package#step-1-install-from-apt-repository

[khteh]

Will it support 25.04?

[Watson1978]

Currently, we have provided the fluent-package for each ubuntu LTS versions.

So, we don't have a plan to support ubuntu 25.04.

It works now.
