SSH CA + gpg-agent + gnuk => error

Tue Sep 29 20:12:08 CEST 2020

I have more, I changed the scdaemon configuration:

fgervais at fgervais-System-Product-Name:~$ cat .gnupg/scdaemon.conf
verbose
debug 2048
log-file /home/fgervais/scdaemon.log

and I got the following:

Would the SIGCONT be the source of my problem?
