Since I have been using Icinga DB (instead of just PostgreSQL) as the backend for my Icinga2 instance, it has happened to me twice that Icinga no longer worked correctly after an update of the Icinga DB package. On closer inspection, it also becomes clear why:
× icingadb.service - Icinga DB Loaded: loaded (/lib/systemd/system/icingadb.service; enabled; preset: enabled) Active: failed (Result: exit-code) since Wed 2025-01-22 21:42:50 CET; 27s ago Duration: 13ms Main PID: 1853805 (code=exited, status=1/FAILURE) CPU: 13ms Jan 22 21:42:50 monitor systemd[1]: Starting icingadb.
