The message:

�[0;33m    Failed to disable unit: Unit file wazuh-manager.service does not exist.�[0m

It was found during manager testing in deployability tests (uninstall process).

It does not interfere with the tests themselves, but its nature should be investigated.

We will attempt to replicate this behavior using Test-manager-complete.yaml.

[joaquinsgi]

The behavior has been replicated, now the test_uninstall.py code will be investigated. Although the test was successful

It will be attempted to replicate the behavior locally, following each of the steps in test_uninstall.py

[joaquinsgi]

The error has been reproduced, and it has been shown that it is due to running the systemctl disable wazuh-manager command after previously uninstalling with the --purge option, which results in the error mentioned in the issue.

After speaking with @rauldpm, the systemctl disable wazuh-manager command will be removed since it was the cause of the error. Since a remove with the --purge option is performed earlier, the uninstallation will be successful, and there will be no need to run the disable command. These changes will be made and tested in the development branch:
