[Touch-packages] [Bug 2055806] Re: sshd.service ssh.socket systemd-tmpfiles-setup:Before= - Missing privilege separation directory: /run/sshd
I think we originally broke this out into a tmpfile since the openssh- server.postinst was calling sshd -G to parse config. However, with the sshd-socket-generator approach, we don't call sshd directly anymore, so we could probably just go back to setting RuntimeDirectory=/run/sshd in ssh.service. -- 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/2055806 Title: sshd.service ssh.socket systemd-tmpfiles-setup:Before= - Missing privilege separation directory: /run/sshd Status in openssh package in Ubuntu: New Bug description: Symptom: ssh.service is not running and not accepting new SSH connections and returns socket closed error upon attempted connection. ssh.service shows a failed with error message "Missing privilege separation directory: /run/sshd".
