It seems that ‘ndd’ is an IDN( Internationalized Domain Names), please install 'idn' command first.

Hello,

I use acme.sh since years now on several Synology NAS for the installation and renewal of their certificats.
Today I have tried to install it on an old DS212 under DSM6.2 but it is not possible to get the certificate because of an IDN command missing.

./acme.sh --issue --server letsencrypt --home .  -d ‘ndd.fr’ –d ‘name.ndd.fr’ -d '*.name.ndd.fr' --dns dns_ovh

I had never seen this message before, and can't go any further as I don't know what to install exactly.

Is there something missing from the last revision of acme.sh or is there a way to solve this issue ?

Thanks for your help.

Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.

acme.sh installed today and it is the latest code.
debug does not provide lot of information

:usr/local/share/acme.sh# ./acme.sh --debug 2 --issue --server letsencrypt --home .  -d 'ndd.fr' -d ‘name.ndd.fr’ -d '*.name.ndd.fr' --dns dns_ovh

Hello,
Problem solved.
It was a copy/past error. Accent and hiden characters were passed to the command line thus leading to the IDN message.
