mux_client_read_packet: read header failed: Broken pipe

[balucio]

I tryed your module on following OpenWrt system

NAME="OpenWrt"
VERSION="2.0.0"
ID="openwrt"
ID_LIKE="lede openwrt"
PRETTY_NAME="OpenWrt 2.0.0"
VERSION_ID="2.0.0"
HOME_URL="%u"
BUG_URL="http://bugs.openwrt.org/"
SUPPORT_URL="http://forum.lede-project.org/"

LEDE_BOARD="sunxi/cortexa7"
LEDE_ARCH="arm_cortex-a7_neon-vfpv4"

LEDE_DEVICE_PRODUCT="Generic"
LEDE_DEVICE_REVISION="1.0.0"
LEDE_RELEASE="OpenWrt 2.0.0 1.0"

using this simple playbook:

---
- hosts: rtus_poste

  roles:
    - ansible-openwrt

  tasks:

    - name: Commit
      uci:
         command: commit

Ansible version 2.9.6 on Linux Mint, I get this error:

Similar error observed in Centos7 and ansible 2.7.5

Hi,

the same for me here:

• pip show ansible | grep Version => Ansible Version: 5.6.0
• ansible --version => ansible [core 2.12.4]
• ansible-galaxy install gekmihesg.openwrt => gekmihesg.openwrt (master)

openwrt.yml:

- hosts: router
  roles:
    - gekmihesg.openwrt
  tasks:
    - name: commit changes
      uci:
        command: commit

ansible-playbook openwrt.yml -u root -k -vvvv => debug3: mux_client_read_packet: read header failed: Broken pipe

full log:

fatal: [router.lan]: FAILED! => {

    "module_stdout": "",
    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",

}

note: with the exact same config, using another task, like opkg, runs successfully.

  tasks:
  - name: test opkg
    opkg: 
      name: tmux

Best regards.

Same here, on any task using uci module.
Ansible 2.16.3 on Ubuntu 24.04
Turris Mox on Turris OS 7.3.0 (OpenWRT 22.03)

Everything works fine on tasks not using uci module.
And this playbook was working fine a few months ago on the same device. So it's probably a regression due to an upgrade somewhere
