I've been using ansible-django-stack for some time now and recently an error has been cropping up with installing security updates on Ubuntu servers (16.04 and 18.04 both have the same issue).
16.04:
SystemError: E:The value 'xenial-security' is invalid for APT::Default-Release as such a release is not available in the sources
18.04:
SystemError: E:The value 'xenial-security' is invalid for APT::Default-Release as such a release is not available in the sources
The task in the playbook is as follows:
- name: Install security updates
apt: default_release={{ ansible_distribution_release }}-security
update_cache=true
upgrade=dist
What happens is that the first time I run the playbook the installation goes fine. Subsequently, however, this error occurs. What would I adjust to make my security updates run as expected when running the playbook?
