Thanks for filing this bug in Ubuntu. The error message is: SSHDConfig: Error: command ['/usr/sbin/sshd', '-T'] failed with exit code 255: /etc/ssh/sshd_config: line 88: Bad configuration option: Y /etc/ssh/sshd_config: terminating, 1 bad configuration options
That means that there is a configuration error in your /etc/ssh/sshd_config file, specifically on line 80. That file isn't attached to this bug report, so I cannot tell you what is wrong. What you should do is open that file, fix what's wrong in line 80, and then you can issue these commands: sudo apt update sudo apt -f install That should retry the operation and this time, if there are no other errors, it should succeed. I'll mark this bug as invalid, since it's a local configuration issue. If you disagree, then feel free to reopen the bug, but please state the reasons why you think it's a valid bug, and steps to reproduce it.
