Ok, so on working images (v20200719 or earlier), google-guest- agent.service is running. On 20210720 or later that service is not included in the systemd boot targets for some reason.
I've checked for system ordering dependency issues which would have disabled the g-g-a.service on the "broken" images and there is nothing at fault there for some reaason it's enabled by not participating in the overall boot target. More triage needed here. # working images have GGA.service enabled and running ubuntu@working-image:~$ cat /etc/cloud/build.info build_name: server serial: 20210719 ubuntu@working-image:~$ sudo systemctl status google-guest-agent.service ● google-guest-agent.service - Google Compute Engine Guest Agent Loaded: loaded (/lib/systemd/system/google-guest-agent.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2021-08-06 19:10:20 UTC; 27min ago Main PID: 717 (google_guest_ag) Tasks: 9 (limit: 8924) Memory: 19.1M CGroup: /system.slice/google-guest-agent.service └─717 /usr/bin/google_guest_agent Aug 06 19:10:26 SRU-worked-gce gpasswd[1323]: user csmith added by root to group dip Aug 06 19:10:26 SRU-worked-gce gpasswd[1329]: user csmith added by root to group video Aug 06 19:10:26 SRU-worked-gce gpasswd[1335]: user csmith added by root to group plugdev Aug 06 19:10:26 SRU-worked-gce gpasswd[1341]: user csmith added by root to group netdev Aug 06 19:10:26 SRU-worked-gce gpasswd[1347]: user csmith added by root to group lxd Aug 06 19:10:26 SRU-worked-gce gpasswd[1353]: user csmith added by root to group google-sudoers Aug 06 19:10:26 SRU-worked-gce GCEGuestAgent[717]: 2021-08-06T19:10:26.2934Z GCEGuestAgent Info: Updating keys for user csmith.
