Thank you for taking the time to file a bug report. While looking at the log files that have been attached to the bug, more specifically to the DpkgTerminalLog.txt file, the following excert has caught my attention:
Nov 13 06:51:37 HP-UP17 systemd[1]: Starting OpenBSD Secure Shell server... Nov 13 06:51:37 HP-UP17 sshd[19069]: /etc/ssh/sshd_config line 68: Directive 'ChallengeResponseAuthentication' is not allowed within a Match block Did you perhaps modify your /etc/ssh/sshd_config file and add a "Match" block containing a "ChallengeResponseAuthentication" directive inside it? If that is the case, then this is not supported by sshd and will prevent its initialization. If you haven't done that, please let us know and we will proceed with the investigation, probably by asking you to provide more information about your setup. Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'. However, if you believe that this is really a bug in Ubuntu, then we would be grateful if you would provide a more complete description of the problem with steps to reproduce, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New".
