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

Question

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 ....

Solution

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.

Is this just once, or is it repeatable? Also, do you get the same results when you enter sudo init 0 in terminal?

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.

what happens if you logout and change to a terminal ctrl-alt-F3 for instance, login, and put into the commandline poweroff

[Thuurio]

@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 ......

This vote puts you over 2000, I see. I wonder if it will switch to 2k? Ah, yes, 1999 - a good year.

@ Mark, any idea how long it will take before Ubuntu will release the bug fix into a new release ?

@Thuurio No, I have no insider information about that. I recommend contacting Ubuntu developers directly about that.
