[Kea-users] DDNS doesn't update local zone

Hi,
I recently upgraded to Devuan Excalibur, equivalent to Debian Trixie, and had
some difficulty starting the Kea daemons. Now they're running. However, a
client somehow got a different IP than it had before.
The host name and PTR records still use the previous IP.
I tried to fix it by issuing dhclient -r/ dhclient. As a result, I have
several records showing the new IP in /var/lib/dhcp4.csv, but the DNS records
are unchanged.
In kea-dhcp4 both enable-updates and ddns-send-updates are set to true.
In both kea-dhcp4.conf and kea-dhcp-ddns.conf I set debuglevel to 99, but, upon
restarting, I only got the two lines
kea-dhcp4: INFO [kea-dhcp4.commands.140267918301120] COMMAND_RECEIVED Received
command 'config-set'
and
kea-dhcp-ddns: INFO [kea-dhcp-ddns.dctl.140298412311744] DCTL_STARTING
DhcpDdns starting, pid: 17117, version: 2.6.3 (stable)
Dhcp releases and subsequent discover, offer, request and ack are not logged.
Is there a way to force the DNS to sync?
Best
Ale
