From the sources it seems that this is intended : https://github.com/systemd/systemd/blob/master/src/systemctl/systemctl-logind.c#L318 However, I report this as a bug since this is against the logic of a scheduled reboot; if someone schedules a reboot they want the system to reboot at the specified time not immediately. There has been a discussion upstream ( https://github.com/systemd/systemd/issues/17575 ) and a PR ( https://github.com/systemd/systemd/pull/18010 ). Upstream community is not willing to accept the patch but debian is. I open this bug to to pull the patch into Ubuntu once it lands in debian. [TEST PLAN] The simpler reproducer is to disable dbus to imitate the real world case. # systemctl stop dbus.service # systemctl stop dbus.socket # shutdown +1140 -r "REBOOT!" Failed to set wall message, ignoring: Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms) Failed to call ScheduleShutdown in logind, proceeding with immediate shutdown: Connection timed out Connection to groovy closed by remote host. Connection to groovy closed. After this patch is applied the shutdown command does not reboot immediately if it fails to schedule the shutdown. Instead it does nothing and returns a non zero return code that can be checked by calling scripts or users. [WHERE PROBLEM COULD OCCUR] This patch changes the behaviour of scheduled reboot in case logind or dbus has failed. Originally, if logind is not available (call to logind bus fails https://github.com/systemd/systemd/blob/master/src/systemctl/systemctl-logind.c#L319) it proceeds with immediate shutdown. This patch changes this behaviour and instead of shutting down it does nothing. The actual regression potential is a user asking for a reboot and not getting it, so the largest regression potential is any existing users (human or programmatic) that are requesting a scheduled shutdown but not checking the return value for error. Any other regression would likely result in the system incorrectly not rebooted, or incorrectly scheduled for reboot. [OTHER] This is now fixed in H, currently affects B,G,F.
