Title:
sshd port migration is missing two config lines from jammy to kinetic
Status in openssh package in Ubuntu:
Fix Committed
Status in systemd package in Ubuntu:
Invalid
Bug description:
The automatic migration script from jammy to kinetic generates a
invalid file for sshd that systemd refuses to read. Manual addition of
two lines is required for a functional sshd with a custom port.
This bug can be considered the opposite of
https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1990863 . They
want to have sshd keep managing the socket while I want to try letting
systemd do that.

# Instructions
- Configure /etc/ssh/sshd_config to port 2222 in 22.04
- Upgrade to 22.10 with sudo do-release-upgrade -d
- Accept overwriting /etc/ssh/sshd_config with the new version
- Attempt to ssh into the machine
# Expected behavior
systemd should listen on port 2222 and start sshd.
$ cat /etc/systemd/system/ssh.socket.d/addresses.conf

# Actual behavior
Port 2222 refuses any connection. Systemd fails to parse the
automatically generated file:

$ cat /etc/systemd/system/ssh.socket.d/override.conf

# Analysis
The migration script must be missing the `[Socket]` line and the next one.
sshd works after I added those two lines manually. Either the migration script
never worked or systemd changed the syntax in the meantime.
