Upgrading from 1.9.5 to 2.0.1.0 without changing the playbook, a task fails
that used to work.
The error:
[DEPRECATION WARNING]: Skipping task due to undefined Error, in the future
this will be a fatal error.. This feature will be removed in a
future release. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.
An exception occurred during task execution. The full traceback is:
Traceback (most recent call last):

PLAY RECAP
*********************************************************************
somehostname : ok=4 changed=1 unreachable=0

The task:
- name: copy apt key files from all roles to /tmp
become: no
copy: src="{{ item.1.path }}/{{ item.1.filename }}" dest="/tmp/{{
item.1.filename }}"
when: "'{{ item.0.role }}' in {{ role_names }} and '{{ item.1.pub }}' not
in ansible_local.installed_apt_keys.key_list"
with_subelements:
- '{{ apt_keys_by_role }}'
- '{{ keyfiles }}'
The relevant variables:
apt_keys_by_role:
- role: common
keyfiles:
- path: "{{ inventory_dir }}/roles/common/files/apt_keys"
filename: linode.gpg
pub: 325A043E
- role: dev
keyfiles:
- path: "{{ inventory_dir }}/roles/dev/files/apt_keys"
filename: nodesource.gpg.key
pub: 68576280
Ideas about what I need to do to fix this for 2.0?
Bonus points: how do you use pdb with Ansible's Python modules? I tried
sticking import pdb; pdb.set_trace() before the line that produces the
IndexError in
/usr/local/lib/python2.7/site-packages/ansible/plugins/lookup/subelements.py,
but that turns the error into a BdbQuit; the (pdb) prompt is printed but it
insta-quits and keeps on going with the task.
