Today I'm trying to reproduce the error in a lxc vm without success: I
logged in via ssh to start the do-release-upgrade there so the system
would initiate sshd on port 1022 as well. The upgrade process went fine
the times I tried it.
Thanks Andreas for spotting the same error in the autopkgtest log. I'm
looking for similarities between it and the horsea machine.
Checking horsea's log, I found the following
"FileNotFoundError: [Errno 2] No such file or directory: '/tmp/ubuntu-
release-upgrader-x6gsdfa4/removal_denylist.cfg'"
in the screenlog.0 under /var/log/dist-upgrade directory:

Title:
upgrade to lunar fails due to rescue-ssh.target or port 22 takeover
Status in openssh package in Ubuntu:
New
Bug description:
Hi,
I just upgraded a system from Jammy to Lunar and openssh-server refuses to
upgrade well.
Setting up openssh-server (1:9.0p1-1ubuntu8) ...
Replacing config file /etc/ssh/sshd_config with new version
Replacing config file /etc/ssh/sshd_config with new version
Synchronizing state of ssh.service with SysV service script with
/lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable ssh
rescue-ssh.target is a disabled or a static unit not running, not starting it.
Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 145.
dpkg: error processing package openssh-server (--configure):
installed openssh-server package post-installation script subprocess
returned error exit status 1
Processing triggers for man-db (2.11.2-1) ...
Processing triggers for libc-bin (2.36-0ubuntu4) ...
Errors were encountered while processing:
openssh-server
Error: Timeout was reached
needrestart is being skipped since dpkg has failed
E: Sub-process /usr/bin/dpkg returned an error code (1)
I'm not sure what exactly it is.
This output complains about rescue-ssh.target and indeed that can not be
started even directly.
$ sudo systemctl start rescue-ssh.target
A dependency job for rescue-ssh.target failed. See 'journalctl -xe' for
details.
And in postinst is a try to start it:
$ grep rescue /var/lib/dpkg/info/openssh-server.postinst
deb-systemd-invoke $_dh_action 'rescue-ssh.target' >/dev/null
|| true
But I think the underlying issue is that ssh is already on, and I'm logged in
via it.
And that makes the service restart of the ssh socket which was added break.
Feb 02 10:40:56 node-horsea systemd[104560]: ssh.socket: Failed to create
listening socket ([::]:22): Address already in use
Feb 02 10:40:56 node-horsea systemd[1]: ssh.socket: Failed to receive
listening socket ([::]:22): Input/output error
Feb 02 10:40:56 node-horsea systemd[1]: ssh.socket: Failed to listen on
sockets: Input/output error
Feb 02 10:40:56 node-horsea systemd[1]: ssh.socket: Failed with result
'resources'.
Now, whichever it is, it is hard to resolve.
The only way to get the socket to own it would be rebooting so that sshd lets
go and systemd can take over.
I could reboot, but that is not the point.
What if I'd want to get the service and upgrade completed before reboot.
Because as of now dpkg considers the system unhappy, and that would usually
be a sign for "better not reboot before being resolved" to me.
One thing though, I have not upgraded with do-release-upgrade - would
we / do we have magic there to make the ssh socket activation
transition smoother?
