I tried installing fluent-bit on Ubuntu 26.04 (on ARM64) and ran into the following issue:

This is not supported currently, I recently did a PR to add it so you will have to wait for the next release.

#11802

There is also a backport to 4.2 so both are just waiting on a release: #11803

I've added it to our downstream distro already to confirm it is fine to release: telemetryforge/agent#294

[patrick-stephens]

Looks like 5.0.6 should include this if you want to confirm and close @yarons?

It seems to work for me in a container at least:

$ docker run --rm -it ubuntu:26.04 bash -c 'apt update && apt install -y gpg curl && curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh'
...
Setting up fluent-bit (5.0.6) ...
Processing triggers for libc-bin (2.43-2ubuntu2) ...

Installation completed. Happy Logging!

I'll have access to this machine on Sunday, sorry for the delay, thanks for the fix.
