DEPENDENCY PROBLEMS

none

STEPS TO REPRODUCE

easy, just specify a group owner in your yaml that is not yet created in the unix file system. For example, the group 'tomcat' below was not created inside of my docker image, therefore unarchive throws the obscure error I mentioned earlier.

- name: Extract cas archive to /var/lib/tomcat8/webapp/cas
  unarchive:
    src: ../target/cas-install.tar.gz
    dest: /
    group: tomcat
    extra_opts: [ "--strip-components=1" ]
  notify: restart services
  when: not ansible_check_mode
  tags: install

EXPECTED RESULTS

I would expect a better message like unix group "tomcat" does not exist

ACTUAL RESULTS

fatal: [localhost]: FAILED! => {"changed": false, "dest": "/", "gid": 0, "group": "root", "handler": "TgzArchive", "mode": "0755", "msg": "Unexpected error when accessing exploded file: [Errno 2] No such file or directory: '/var/lib/tomcat8/webapps/cas/META-INF'", "owner": "root", "size": 4096, "src": "/root/.ansible/tmp/ansible-tmp-1549494633.45-18088113372762/source", "state": "directory", "uid": 0}
