`service` fails on second host

Question

`service` fails on second host

giorgiga opened this issue 2 years ago · 4 comments

I'm using

- name: disable services
  service:
    name: "{{ item }}"
    enabled: no
    state: stopped
  loop:
    - odhcpd
    - dnsmasq
    - firewall

for my two wifi access points.

Whenever I run ansible targeting both hosts, the task succeeds on the first AP, but always fails on the second with:

failed: [ap2] (item=dnsmasq) => {
    "ansible_loop_var": "item",
    "changed": false,
    "item": "dnsmasq",
    "rc": 127
}

MSG:

The module failed to execute correctly, you probably need to set the interpreter.
See stdout/stderr for the exact error


MODULE_STDOUT:

/bin/sh: /usr/bin/python: not found

If I run ansible with --limit either one of the two APs (tried both) it works flawlessly.

ansible 2.12.17 on Fedora f36 with latest gekmihesg.ansible-openwrt

Answer 2 · 2022-09-19T16:01:01.000Z

It seems like it tries to use ansible's default service instead of the openwrt one? (Using module file /usr/lib/python3.10/site-packages/ansible/modules/service.py)

Answer 3 · 2023-09-26T06:03:12.000Z

@giorgiga how to solve it, same error when i use loop with include_tasks,
It loads the default module ‘ansible/modules/command.py’ instead of ‘.ansible/roles/gekmihesg.openwrt/library/openwrt_command.sh’

Personally, I've ended up ditching ansible and building custom openwrt images with the imagebuilder instead: running ansible without python on the target host is just too much of a pain.

PS: IDK why it says I've closed this issue... I must have closed it when I was high :)
