I have confirmed the fix using openssh-server 1:9.6p1-3ubuntu13.9 from
noble-proposed:
First, I confirmed the bug was present on this system:
root@noble:~# cat > /etc/ssh/sshd_config.d/custom.conf << EOF
> Port 1234
> Match LocalPort 22
PasswordAuthentication no
EOF
root@noble:~# /lib/systemd/system-generators/sshd-socket-generator .
'Match LocalPort' in configuration but 'lport' not in connection test
specification.
Then I installed openssh-server from noble-proposed:
root@noble:~# cat > /etc/apt/sources.list.d/proposed.sources << EOF
Types: deb
URIs: http://us.archive.ubuntu.com/ubuntu/
Suites: noble-proposed
Components: main universe
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF
root@noble:~# apt update && apt install -t noble-proposed openssh-server -y
