Thank you for taking the time to report this bug and helping to make Ubuntu better. Feedback on this is appreciated as we do want to make the transition as smooth as possible.
I would warn though that just overwriting configuration files with "known good" ones following a release upgrade, as you're doing with Ansible, is not advisable in the general case, and cannot be a supportable path in packaging. Because a release upgrade means major version bumps by definition, and configuration file syntaxes change. The assumption of "known good" therefore cannot be made in release upgrades. Therefore, I'm not sure the upgrade path can really be improved here. You can't assume that you can overwrite configuration with what you had in a previous release without looking into the details of how your previous change may no longer apply correctly. What we can do is improve documentation on this, but the documentation has yet to be written because Kinetic hasn't been released yet. The documentation is expected to appear in the release notes at https://discourse.ubuntu.com/t/kinetic-kudu-release-notes/27976, which is the usual place for us to note upgrade path edge cases. I wonder if there's some conflict here between the conffile (or ucf?) prompt and the upgrade path handling, so I subscribed Steve to take a look. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1990863 Title: conversion from sshd service to socket is too bumpy Status in openssh package in Ubuntu: New Bug description: During upgrade from Jammy to Kinetic, I get asked what to do because my sshd_config has been modified. I say to do a 3-way merge. It says 3-way merge fails. I shrug, figure I'll just restore my customizations with Ansible after the upgrade like I always do, and tell it to use the vendor version of the file. This removes my custom Port settings, so they are not migrated over to the ssh.socket settings like https://discourse.ubuntu.com/t/sshd-now-uses-socket-based-activation- ubuntu-22-10-and-later/30189 says they would be. I subsequently run my Ansible which restores the customizations and enables the ssh service, but now ssh.service and ssh.socket are enabled at the same time, sshd isn't listening on my specified ports, and everything is a mess. I've never used socket-based activation before and have no idea how to configure it so now I have to go reading man pages, Googling all over the place, and generally struggle to figure out what the heck is going wrong. I don't know what the right answer is here, but I really feel like some effort needs to be put into figuring out a smoother transition for people who are upgrading to Kinetic.
