…ptions Disable unattended-upgrades and apt timers to prevent mid-job interruptions. Library upgrades (e.g., libglib2.0) trigger libc-bin processing which causes systemd to restart services, sending SIGTERM to semaphore-agent and killing running CI jobs. - Disable apt-daily.timer and apt-daily-upgrade.timer - Stop unattended-upgrades service - Configure apt to disable automatic upgrades - Add documentation explaining the change

👋🏻 Can we also disable unattended-upgrades at instance launch time (not just during AMI build)? This would ensure consistency between the baked AMI and running instances. Simply purging the package should cover all cases - it removes the service, timers, and config files in one task: - name: Remove unattended-upgrades package
ansible.builtin.apt:
name: unattended-upgrades
state: absent
purge: yes
tags:
- disable_unattendedThis is simpler than the current approach of stopping services + writing config files, and achieves the same result. |
Replace multi-step approach (stopping services, disabling timers, writing config files) with single package purge. Also add purge at instance launch to ensure consistency between baked AMI and running instances.
