Hi,
Moving from 7.0.10 on Debian Trixie to 8.0.4 installed through backports repo.
With a fresh config file, or using existing, I just get this failure trying to start the service:
systemd[1]: suricata.service: Failed with result 'protocol'.
suricata -T passes just fine. Only errors in the logs are as follows:
[1073623 - Suricata-Main] 2026-04-24 23:28:17 Notice: threads: Threads created -> W: 4 FM: 2 FR: 2 Engine started.
[1073623 - Suricata-Main] 2026-04-24 23:28:17 Notice: suricata: Signal Received. Stopping engine.
[1073623 - Suricata-Main] 2026-04-24 23:28:18 Info: suricata: time elapsed 1.978s
Any insight? I let suricata-update run to make sure the ruleset was updated for version 8.
Many thanks
