Ansible error on vagrant up

I’m trying to get the base install working and am getting an error:

ERROR: apt_key is not a legal parameter in an Ansible task or handler

The relevant line in main.yml:

apt_key: url="http://keyserver.ubuntu.com/pks/lookup?op=get&fingerprint=on&search={{ keyserver_fingerprint }}"
state=present

Any ideas?

What version of Ansible are you using?

@Foxaii Current version is 1.8 according to VERSION file.

OK, solved it by uninstalling ansible and reinstalling, this time via pip. Nothing to see here…
