Hello Arnold, I thank you for your answer.
It looks like openssh-server was not installed. Then, I installed it and I have this message after doing a "sshd -t" : Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_ecdsa_key Could not load host key: /etc/ssh/ssh_host_ed25519_key The folder /var/run/sshd exists but have nothing inside it. Hope this will resovle the issue.
