Tasks "download alertmanager binary to local folder" and "unpack alertmanager binaries" always changed

[meons]

What happened?

These tasks are always have changed state in normal and check mode as well. But they shouldn't make noise if alertmanager is already installed.

TASK [cloudalchemy.alertmanager : download alertmanager binary to local folder] ***
changed: [myhost]
TASK [cloudalchemy.alertmanager : unpack alertmanager binaries] ****************
changed: [myhost]

Did you expect to see some different?

After a first successful run, these tasks shouldn't have changed state in next runs (if there is no changes on host of course).

How to reproduce it (as minimally and precisely as possible):

Install this role on a Ubuntu 20.04.1 LTS.

Environment

• Role version:

  0.19.1

• Ansible version information:

• Variables:

• Ansible playbook execution Logs:

Anything else we need to know?:

Are the check_mode: false statements correctly used here?
