For both tw VERSION_ID 20211120 (libunbound8-1.13.2-2.1), and VERSION_ID 20211220 (libunbound8-1.14.0-1.1), I could see the segv. A forced --oldpackage downgrade to a safekept libunbound8-1.13.1-2.1, once more fixes the problem even with 20211220 state of the world, so is a viable workaround. This time, I got a coredump recorded from the 1.14.0 case, and for your kind consderation, attach its analysis here. It clearly shows a null pointer issue. ============================================= Core was generated by `/usr/sbin/opendkim -f -x /etc/opendkim/opendkim.conf'.
