Error (syslog): [Wed Mar 29 08:05:59 2023] audit: type=1400 audit(1680069960.544:88): apparmor="DENIED" operation="open" profile="kea-lfc" name="/etc/resolv.conf" pid=6641 comm="kea-lfc" requested_mask="r" denied_mask="r" fsuid=102 ouid=0 The problem can be solved by doing this (but not sure if that's intended): diff /tmp/usr.sbin.kea-lfc.orig /etc/apparmor.d/usr.sbin.kea-lfc 13a14 > /etc/resolv.conf r, And then restarting apparmor solved this.
