Public bug reported: 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. $ lsb_release -rd Description: Ubuntu Kinetic Kudu (development branch) Release: 22.10 $ apt-cache policy openssh-server openssh-server: Installed: 1:9.0p1-1ubuntu6 Candidate: 1:9.0p1-1ubuntu6 Version table: *** 1:9.0p1-1ubuntu6 500 500 https://gpl.savoirfairelinux.net/pub/mirrors/ubuntu kinetic/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy systemd systemd: Installed: 251.4-1ubuntu6 Candidate: 251.4-1ubuntu6 Version table: *** 251.4-1ubuntu6 500 500 https://gpl.savoirfairelinux.net/pub/mirrors/ubuntu kinetic/main amd64 Packages 100 /var/lib/dpkg/status # 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 [Socket] ListenStream= ListenStream=2222 $ systemctl status ssh.socket ● ssh.socket - OpenBSD Secure Shell server socket Loaded: loaded (/lib/systemd/system/ssh.socket; enabled; preset: enabled) Drop-In: /etc/systemd/system/ssh.socket.d └─addresses.conf Active: active (running) since Thu 2022-09-29 02:08:56 EDT; 9min ago Until: Thu 2022-09-29 02:08:56 EDT; 9min ago Triggers: ● ssh.service Listen: [::]:2222 (Stream) Tasks: 0 (limit: 19047) Memory: 8.0K CPU: 923us CGroup: /system.slice/ssh.socket Sep 29 02:08:56 daniel-desktop2 systemd[1]: Listening on OpenBSD Secure Shell server socket. # Actual behavior Port 2222 refuses any connection.
