What can be a reason for last -x reboot showing two last entries as still running? Besides, I'm pretty sure I did not reboot this server December, 16, though it could be something with power on hosting provider. If that was the case, would this be expected result?

root@cthulhu-new ~ # last -x reboot
reboot   system boot  4.13.0-0.bpo.1-a Sat Dec 16 06:26   still running
reboot   system boot  4.13.0-0.bpo.1-a Thu Dec  7 07:56   still running
reboot   system boot  4.13.0-0.bpo.1-a Wed Dec  6 11:10 - 07:55  (20:44)

wtmp begins Tue Dec  5 19:59:27 2017

Here's the output of last -x shutdown which has no entry for Dec 16:

root@cthulhu-new ~ # last -x shutdown
shutdown system down  4.13.0-0.bpo.1-a Thu Dec  7 07:55 - 07:56  (00:00)
shutdown system down  4.13.0-0.bpo.1-a Wed Dec  6 11:10 - 11:10  (00:00)

wtmp begins Tue Dec  5 19:59:27 2017

  • Give a try to tuptime -t. It have a clear output.

Yes, it would be the expected result. last doesn’t know that your system was shut down on December 16, presumably because it wasn’t an orderly shut down (power loss or something like that). Because of the way it displays boots, it considers that the last two boots are still running.

Things will sort themselves out to some extent the next time the system is shut down; last will then use the new shut down time for both December 7 and 16 boots.
