The above look very bad too me. Imho /README.txt shouldn't be there at all. Not sure why /media is owned by nvidia:nvidia, usually /media is owned by root. Ditto / and /lib should be owned by root. It is a security vulnerability for unpriviledged user to own these top level directories. Can you please try this: $ sudo chown root:root / /lib /media And check if systemd-tmpfiles works after that? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1811580 Title: systemd fails to start sshd at reboot Status in systemd package in Ubuntu: Confirmed Bug description: Ubuntu 16.04.5, systemd 229-4ubuntu21.15 The latest systemd update has somehow changed the method it uses to start 'ssh.service' i.e. 'sshd'. systemd fails to start sshd if /etc/ssh/sshd_config contains "UsePrivilegeSeparation yes" and /var/run/sshd/ does not already exist. Being as this is the default, virtually EVERY Ubuntu 16.04 server in the world has UsePrivilegeSeparation set to yes. Furthermore, at the time when the user performs 'apt upgrade' and receives the newest version of systemd, /var/run/sshd/ already exists, so sshd successfully reloads for as long as the server doesn't get rebooted. BUT, as soon as the server is rebooted for any reason, /var/run/sshd/ gets cleaned away, and sshd fails to start, causing the remote user to be completely locked out of his system. This is a MAJOR issue for millions of VPS servers worldwide, as they are all about to get locked out of their servers and potentially lose data. The next reboot is a ticking time bomb waiting to spring. The bomb can be defused by implicitly setting 'UsePrivilegeSeparation no' in /etc/ssh/sshd_config, however unsuspecting administrators are bound to be caught out by the millions. I got caught by it in the middle of setting up a new server yesterday, and it took a whole day to find the source. The appropriate fix would be to ensure that systemd can successfully 'start ssh.service' even when 'UsePrivilegeSeparation yes' is set. systemd needs to test that /var/run/sshd/ exists before starting sshd, just as the init.d script for sshd does. openssl could also be patched so that UsePrivilegeSeparation is no longer enabled by default, however that is not going to solve the problem for millions of pre- existing config files. Only an update to openssl to force-override that flag to 'no' would solve the problem. Thus systemd still needs to be responsible for ensuring that it inits sshd properly by ensuring that /var/run/sshd/ exists before it sends the 'start' command.
