# Playbook to update SecureDrop VMs configured with the latest stable release
# to use the release candiate packages from apt-test.freedom.press (rather
# than apt.freedom.press). Updates the apt repo pubkey with a testing pubkey,
# and alters the apt source lists to point to the test server.
#
# Steps to use this playbook:
#
#   1. `git checkout 0.7.0`
#   2. Provision prod VMs.
#   3. Switch to Admin Workstation.
#   4. `./securedrop-admin tailsconfig`
#   5. `source .venv/bin/activate` (so ansible commands work)
#   6. `cd install_files/ansible-base`
#   7. `ansible-playbook -vv --diff securedrop-qa.yml`
#   8. `ssh app` # start interactive session
#   9. `sudo cron-apt -i -s`
#   10. Repeat steps 8 & 9 on mon.
