I’m encountering the following error:
Unexpected Exception: ‘module’ object has no attribute ‘_vendor’
My environment is:
Ubuntu 15.10
Python 2.7
Ansible 2.0 (via the ppa at http://ppa.launchpad.net/ansible/ansible/ubuntu)
VirtualBox 5.0.10
After performing an OS update today, Ansible moved from 1.9.4 to 2.0. At that point I started encountering the error. Uninstalling and reinstalling Ansible did not resolve the error. Uninstalling Python and Ansible, then reinstalling Ansible (via apt-get) did resolve the error. However, after reinstalling VirtualBox 5.0.10 (along with its many Python related dependencies), the error resurfaced.
For the moment, I’m sure I’ll attempt to lock Ansible to 1.9.4, but I’m interested if anyone has feedback related to why this may be occurring and what I may be able to do to resolve the issue.
Here’s the full stack trace:
(the log file is writable by the user, which makes for a puzzling warning message as well).
