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?
