Unit sshd.service not found

Question

Good morning to all, I've a problem with ssh. I'm using Ubuntu 23.10, new installation. I've installed openssh-server via

sudo apt install openssh-server

However, when I try to use something related to sshd, e.g.

sudo systemctl start sshd

or

sudo service sshd restart

I've the following error:

Failed to start sshd.service: Unit sshd.service not found

or

Failed to restart sshd.service: Unit sshd.service not found

I've tried to purge openssh several times and in different ways:

sudo apt-get remove --purge openssh-server
sudo apt purge openssh-server
sudo apt autoremove
sudo apt remove ssh --purge -y

and I've tried different ways to reinstall:

sudo apt install openssh-server
sudo apt-get install openssh-server
sudo apt install ssh -y

But I've failed every time. The file in \etc\ssh\sshd_config is correctly installed.

What can be the problem? How can I solve it? Thanks in advice for your help

EDIT

This is the file list according to

dpkg -L openssh-server

file list

Answer 1

Use given command to restart the ssh service

systemctl restart ssh

As per my knowledge sshd is for Centos, Not for Ubuntu
