No, the reason was the wrong "{{ item.item }}" reference.
Real world example:
- name: TEST - Check /tmp/out.log for some lines expected to be there
tags: test
lineinfile:
path: /tmp/out.log
regexp: "{{ item.item }}"
state: absent
check_mode: yes
changed_when: false
register: checklog
with_items:
- { item: "^v=1"}
- { item: "^s=Kurento Media Server" }
- { item: "^IceCandidateFound" }
- { item: "^IceGatheringDone" }
failed_when: not checklog.found
The failing line is "v=1", because it is "v=0". The rest of the lines
except the last is there. Result:
TASK [TEST - Check /tmp/out.log for some lines expected to be there]
******************************************************************************************************************************************************************
failed: [ubuntuVM] (item={'item': '^v=1'}) => {"ansible_loop_var": "item",
"backup": "", "changed": false, "failed_when_result": true, "found": 0,
"item": {"item": "^v=1"}, "msg": ""}
ok: [ubuntuVM] => (item={'item': '^s=Kurento Media Server'}) =>
{"ansible_loop_var": "item", "backup": "", "changed": false,
"failed_when_result": false, "found": 1, "item": {"item": "^s=Kurento Media
Server"}, "msg": "1 line(s) removed"}
ok: [ubuntuVM] => (item={'item': '^IceCandidateFound'}) =>
{"ansible_loop_var": "item", "backup": "", "changed": false,
"failed_when_result": false, "found": 12, "item": {"item":
"^IceCandidateFound"}, "msg": "12 line(s) removed"}
failed: [ubuntuVM] (item={'item': '^IceGatheringDone'}) =>
{"ansible_loop_var": "item", "backup": "", "changed": false,
"failed_when_result": true, "found": 0, "item": {"item":
"^IceGatheringDone"}, "msg": ""}

ubuntuVM : ok=1 changed=0 unreachable=0

So it works as expected
Solved.
