/etc/ssh/sshd_config: line 11: Bad configuration option: Include

This error message indicates that there is an incorrect configuration option in the /etc/ssh/sshd_config file on line 11. The option "Include" is not recognized as a valid configuration option in the sshd_config file.

To resolve this issue, you can either remove the "Include" option from line 11 or make sure that it is followed by a valid configuration file path.

For example, if you intended to include another configuration file, you can use the following syntax:

Include /etc/ssh/sshd_config.d/*.conf

This will include all the configuration files with .conf extension in the /etc/ssh/sshd_config.d/ directory.

After making the necessary changes to the sshd_config file, save it and restart the SSH service to apply the changes:

sudo systemctl restart sshd
