Hello, following doesn’t work: % nl -ba OS.yml 1 — 2 - hosts: all 3 tasks: 4 - name: print Ubuntu 5 shell: echo Ubuntu 6 when: ansible\_os\_family == “Ubuntu” 7 8 - name: print Debian 9 shell: echo Debian 10 when: ansible\_os\_family == “Debian” Do you have an idea? Thnx, regards 🙂 ---

ansible\_os\_family for Ubuntu is Debian, by design, as it’s in the Debian family. Similarly, Fedora is a Red Hat derived distribution, as is CentOS. You should use a different fact. see “ansible hostname -m setup” for all available facts.
