TASK [Run the role with previous=replaced only] ********************************
task path: /tmp/collections-NBd/ansible_collections/fedora/linux_system_roles/tests/postfix/tests_previous_replaced.yml:5
ERROR! the role 'fedora.linux_system_roles.postfix' was not found in /tmp/collections-NBd/ansible_collections/fedora/linux_system_roles/tests/postfix/roles:/root/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/roles:/tmp/collections-NBd/ansible_collections/fedora/linux_system_roles/tests/postfix

The error appears to be in '/tmp/collections-NBd/ansible_collections/fedora/linux_system_roles/tests/postfix/tests_previous_replaced.yml': line 7, column 15, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

      include_role:
        name: fedora.linux_system_roles.postfix
              ^ here
