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

The nsupdate script (/tmp/tmp.17EBRdeI8j) is here (with truncated TXT) :
server 10.42.42.21
zone durel.eu.
origin durel.eu.
ttl 600
add _acme-challenge.ns.durel.eu. 600 in TXT "qLH_KkbQ_IUVr[...]7rs-iUE"
send
quit
As I can reproduce this with any tsig key, I can provide a core if you
need it.
