I have some ansible that failes on one node just running ansible.builtin.shell yum commands the rc code 100  
which doesnt seem to be an error at all?

- **yum check-update** returns exit value of 100 if there are packages available for an update. Also returns a list of the packages to be updated in list format.

any idea what I am doing wrong?

```auto
    - name: yum list
      ignore_errors: yes
      ansible.builtin.shell: yum check-update --exclude=389-ds* --disablerepo=* --enablerepo=rhui* > /root/{{ inventory_hostname }}.txt

```

```auto
TASK [yum list] *****************************************************************************************************************************************************************************
fatal: [SISLIC]: FAILED! => {"changed": true, "cmd": "yum check-update --exclude=389-ds* --disablerepo=* --enablerepo=rhui* > /root/SISLIC.txt", "delta": "0:00:09.812078", "end": "2026-02-17 08:55:36.440690", "msg": "non-zero return code", "rc": 100, "start": "2026-02-17 08:55:26.628612", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}

```

ansible assums that any return code that is not 0 (zero) indicates failure of the command. As you mentioned return code is 100, so ansible fail.

See in the log you provided ““msg”: “non-zero return code”, “rc”: 100,“

```yaml
- name: yum list
  ansible.builtin.shell: yum check-update --exclude=389-ds* --disablerepo=* --enablerepo=rhui* > /root/{{ inventory_hostname }}.txt
  failed_when: false

```

adding directive ‘failed\_when’ should help.  
There is another more precise approach:

```yaml
- name: yum list
  ansible.builtin.shell: yum check-update --exclude=389-ds* --disablerepo=* --enablerepo=rhui* > /root/{{ inventory_hostname }}.txt
  register: yum_check_update
  failed_when: yum_check_update.rc not in [0,100]

```

This will fail only if return code (see ‘.rc’) is not 0 or 100.

Generally you should not use ignore\_errors, see [https://medium.com/@sbarnea/why-ansible-ignore-errors-is-evil-500fb6e81229](https://medium.com/@sbarnea/why-ansible-ignore-errors-is-evil-500fb6e81229)

Right, that’s the case. According `man yum`

The 100 means just, there are updates available and a list of them is provided. According the return code the case needs then to be addressed appropriate, in example as shown in the given answer.
