I just installed Ubuntu 18.04 Developer version minimal install, on my Asus N750 JK laptop.

When I shutdown Ubuntu this error appears quickly:

systemd shutdown [1] Failed to wait for process : protocol error

but my laptop still shuts down.

Any idea what is going on? Do I have to worry?

$ systemd --version
systemd 237 ....

    Is this just once, or is it repeatable? Also, do you get the same results when you enter sudo init 0 in terminal? – SDsolar Jun 11 '18 at 0:18

    Every time I shutdown my laptop. This morning I notice that the message also appears when you reboot. sudo init 0 in the terminal gives the same result. – Thuurio Jun 11 '18 at 11:08

    what happens if you logout and change to a terminal ctrl-alt-F3 for instance, login, and put into the commandline poweroff – abu_bua Jun 11 '18 at 13:12
  • @abu_bua : When I shutdown my laptop I only have 3 options Cancel / Restart / Poweroff. I click on poweroff and switch on my laptop again. On the login screen I pressed ctrl-alt-F3 and it switch to a terminal screen and there I log in and carry out the poweroff command and the result was : No message appear...... I see that mark already answer the question ...... – Thuurio Jun 11 '18 at 23:18

Welcome to Ask Ubuntu.

By searching for "[Failed to wait for process: protocol error]", I found there was a related systemd bug report about it.

A fix was merged fairly recently.. Perhaps Ubuntu will provide the update in a future update to 18.04.

  • This vote puts you over 2000, I see. I wonder if it will switch to 2k? Ah, yes, 1999 - a good year. – SDsolar Jun 11 '18 at 16:58
  • @ Mark, any idea how long it will take before Ubuntu will release the bug fix into a new release ? – Thuurio Jul 3 '18 at 11:45
  • @Thuurio No, I have no insider information about that. I recommend contacting Ubuntu developers directly about that. – Mark Stosberg Jul 16 '18 at 16:07
