Kea DHCP fails to start after upgrade to 26.1.8

[flyingbird76]

Hi

I upgraded from 26.1.7 to 26.1.8 last night and all was OK initially. I did not rebout Opnsense after the upgrade as i'm not using Captive Portal (with or without IPv6).

This morning I restarted the firewall and when it came backup, the Kea DHCP service failed to start and I cannot start it manually.

Viewing log under services>>Kea DHCP shows nothing (it is blank - I cleared it before restarting Kea so I could see latest errors).

Viewing System>>Log File>>General shows the following (again cleared it before restarting Kea service)

Last day
2026-05-13T11:04:46Noticeopnsense/usr/local/sbin/pluginctl: plugins_configure kea_sync (execute task : kea_configure_do(1))
2026-05-13T11:04:46Noticeopnsense/usr/local/sbin/pluginctl: plugins_configure kea_sync (1)

To get my environment up an running again (all my devices use DHCP reservations), i had to quickly export my DHCP reservations from Kea, reformat them, and import them into DNSMasq which is have enabled for DHCP only.

I would prefer to keep using Kea instead of DNSMasq for DHCP.

How can I track down why Kea is no longer starting when the logs are not showing any info?

Is anyone else having similar issues with Kea after upgrading to 26.1.8?

Thanks in advance.

We hotfixed it today, search for updates.

It was a very KEA thing, here some references:

Thanks for letting me know. I had tried an update before posting incase there was a hotfix, but nothing showed up at first. I had to change my mirror back to default before the updates showed up.

All sorted now.

Thanks again.
