[knot-dns-users] Re: knsupdate Segmentation fault

Hello, Since I upgraded to 3.2.2-cznic.1~bullseye, my scripts using knsupdate fails, on every machine they run on. I can reproduce this with gdb, here is the trace I get in this case : Starting program: /usr/bin/knsupdate -k /etc/letsencrypt.sh/hooks/tsig.key /tmp/tmp.17EBRdeI8j [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
