[Bug 2087551] Re: OpenSSH server config broken on unattended update

[Nick Rosbrook]

So far I cannot reproduce anything like you are describing. Any other
logs from ssh.service and ssh.socket would be helpful.

Since it appears you have another way to gain shell access besides ssh,
are you able to test if the problem persists if you attempt to restore
the socket activation configuration?

Title:
  OpenSSH server config broken on unattended update

Status in openssh package in Ubuntu:
  Incomplete

Bug description:
  My server performed unattended update of openssh-server from
  1:9.6p1-3ubuntu13.5 to 1:9.6p1-3ubuntu13.7, and after this I could not
  access ssh anymore, connection refused.

  Following the steps at the bottom of this post to use non-socket-
  based-activation has allowed me to connect to the server again:

  https://discourse.ubuntu.com/t/sshd-now-uses-socket-based-activation-
  ubuntu-22-10-and-later/30189

  I suspect this is related to using a non-default port, although the
  systemd socket configuration appeared to exist with correct values, as
  well as the custom port value in sshd_config, before making the above
  change.
