Someone or some thing halted Ubuntu this evening at just after 8pm. I do not know what, could not locate anything in the logs.
At this point I’ve removed public access to systemctl, removed a number of graphical reboot/shutdown tools, and performed an early upgrade of the kernel on this machine in case it is a kernel bug.
If you happen to notice the machine goes aware right after you do something, please let me know what that something is. E-mail firstname.lastname@example.org. Thank you.
