Hi Huy,

The bug report appears to indicate some sort of syntax error in your /etc/ssh/sshd_config file. What's on line 13 of that file?

SSHDConfig:
 Error: command ['/usr/sbin/sshd', '-T'] failed with exit code 255: /etc/ssh/sshd_config: line 13: Bad configuration option: Include
 /etc/ssh/sshd_config: terminating, 1 bad configuration options

If you're uncertain, then can you please attach your /etc/ssh/sshd_config for us to review? If that file contains any information that is security sensitive or personally identifying please change this bug report from "Public" to "Private". Thanks ahead of time.
