Journal ends with: Sep 02 23:59:22 nuc systemd-shutdown[1]: Sending SIGTERM to remaining processes... Sep 02 23:59:22 nuc systemd-journald[1455]: Journal stopped
which means that something is not dieing and we are not getting any more logs recorded..... and it indicates that all/most attempts to reboot have been exhausted and possibly it is the firmware/bios itself that are failing to reboot/shutdown the machine. What are exact model details of the affected machines? maybe we can find same/similar in the validation lab and check if they pass Ubuntu certification. -- 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/1619844 Title: [Xenial] shutdown/reboot hangs at "Reached target Shutdown" Status in systemd package in Ubuntu: Confirmed Bug description: I tried getting more information in the debug-shell but I was unsuccessful in doing so. I was able to switch to the debug shell via ctrl+alt+f9 but I couldn't actually type anything in. I could switch back to the stuck shutdown screen via ctrl+alt+f1, and hitting NumLock would turn the light on my keyboard on and off, but I couldn't do anything else. I captured a journal of the stuck reboot. Interestingly, the journal shows a few more lines after "Reached target Shutdown", which is as far as I get on my screen. This system was installed with Xenial 16.04.1 (never been upgraded) and has had this problem since the very first boot.
