Does Github Actions support anything but Ubuntu?

Question

I see in my Github actions

runs-on: ubuntu-latest

What other distros are available? For example, can I run on Alpine or Debian?

Answer 1

No

Github only supports Ubuntu as of 2024 (and osx, and windows). You can see the list of supported runners for

• public repositories
• private repositories

You can find the source code for the runners here.
