package openssh-server 1:8.2p1-4ubuntu0.5 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 1

[Frank Nemec]

I had fixed an earlier problem with /etc/ssh/sshd_config but this error persists. I've tried removing the package, rebooting, and adding the openssh-server. package.

Thanks for taking the time to report this bug and trying to make Ubuntu better.

From the sshd logs in the description we can see:

 Error: command ['/usr/sbin/sshd', '-T'] failed with exit code 255: /etc/ssh/sshd_config: line 125: Bad configuration option: Host
 /etc/ssh/sshd_config: line 126: Bad configuration option: ForwardX11
 /etc/ssh/sshd_config: terminating, 2 bad configuration options

Which tells us that your sshd_config file has some bad configuration on line 125 and 126. Please, revisit your configuration file and fix it up.

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".
