Playbook failing execution due to permission denied - ansible

Question

Here is the inventory content:
[osm]
osm_host ansible_port=22 ansible_host=10.20.20.11 ansible_user=ubuntu ansible_ssh_private_key_file=/path/to/key/key
And here is the playbook content:
- hosts: osm
user: ubuntu
become: yes
tasks:
- name: Download the OSM installer
get_url: url=https://osm-download.etsi.org/ftp/osm-8.0-eight/install_osm.sh dest=/tmp/install_osm.sh
- name: Execute the OSM installer
shell: /tmp/install_osm.sh
When I run ansible-playbook -i inventory play.yaml, I get the following error:
PLAY [osm]
TASK [Gathering Facts]
********************************************************* ok: [osm_host]
TASK [Download the OSM installer]
********************************************** ok: [osm_host]

PLAY RECAP
********************************************************************* osm_host : ok=2 changed=0 unreachable=0

I tried to use true and yes for the become clause, but nothing changed. What am I missing?

You have to be sure that the root user has executable permissions on the new OSM download. When you use a become: yes without become_user, the default user is root
So you need to be sure that root user can execute your script.
Try the get_url like that:
- hosts: osm
user: ubuntu
become: yes
tasks:
- name: Download the OSM installer
get_url:
url: https://osm-download.etsi.org/ftp/osm-8.0-eight/install_osm.sh
dest: /tmp/install_osm.sh
mode: "0555"
- name: Execute the OSM installer
shell: /tmp/install_osm.sh
Play with the mode param of the get_url module.
