[Bug 1750754] Re: package openssh-server 1:7.5p1-10ubuntu0.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Hi,
from your log:
SSHDConfig: Error: command ['/usr/sbin/sshd', '-T'] failed with exit code 255: Missing privilege separation directory: /run/sshd

Log:
Feb 21 18:47:43 turagit01 sshd[3829]: error: Bind to port 22 on 192.168.1.15 failed: Cannot assign requested address.
Feb 21 18:47:43 turagit01 sshd[3829]: fatal: Cannot bind any address.
Feb 21 18:47:43 turagit01 systemd[1]: ssh.service: Main process exited, code=exited, status=255/n/a

Those seem to be two separate issues, the one thing they share is that
they seem to be cusotm configuration that has gone wrong.

sshd -T is the "test my config" before it starts.
If you fix the configuration of your ssh server I'm pretty sure the upgrade will succeed.

See [1] for an example how to restore a conffile to the original version
if you don't want to edit your changes manually, but just revert.
