Please anyone have a tip on how I can solve this problem?

kea-dhcp6: RTNETLINK answers: Operation not permitted

I am using:
https://github.com/zorun/kea-hook-runscript/blob/master/examples/ipv6_prefix_delegation/ipv6-routes.sh
+
https://code.ffdn.org/zorun/kea-hook-runscript/-/jobs/243/artifacts/file/kea-hook-runscript-kea-1-8-debian-buster.so
+
isc-kea-dhcp6-server 1.8.2-isc0001520201206093433 amd64 ISC Kea IPv6 DHCP server

My setup: Debian 11 + kernel 5.10.0-3-amd64

many thanks

Is it possible that Kea is not running as root in your setup? In that case, the script will also not run as root, and you won't be able to add/remove routes.

Yep - you're right. Kea is running as "_kea".

Resolved: install sudo + _kea ALL=(ALL) NOPASSWD: /bin/ip -6 route *

All is working now - many thanks @zorun good job
