If I try to launch Nautilus in whatever way (from Unity, Terminal), it doesn't launch. Terminal gives me these outputs:


name@machine:~$ nautilus

(nautilus:4367): GLib-GIO-ERROR **: Settings schema 'org.gnome.nautilus.preferences' is not installed

Trasovací/ladící past (SIGTRAP) (core dumped [obraz paměti uložen])

launch with sudo

name@machine:~$ sudo nautilus

(nautilus:4672): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

I tried to reinstall Nautilus (with purge), reboot, remove ~/.config/nautilus, step by step at first and then all at once but nothing worked. I haven't changed any configuration or made any significant changes in Ubuntu system since installation. Yesterday Nautilus worked, today doesn't. Does anybody know how to fix it?

    After seeing what you have tried already, this looks like something you can't fix yourself. I suggest you report this as a bug at bugs.launchpad.net. – Jos May 10 '16 at 8:32

The schema org.gnome.nautilus.preferences is defined in the file /usr/share/glib-2.0/schemas/org.gnome.nautilus.gschema.xml which is in the package nautilus-data. Maybe it got damaged somehow.


sudo apt-get install --reinstall nautilus-data

to install that package again.

  • That file had been missing completely. Solution worked, thank you. I thought it could be caused by some broken or missing file. Are you specialist or do you found out that somehow? Is there a way how to recognize, which package has broken or missing file (at least the missing one, broken files are always difficult to spot)? Why nautilus-data cannot be removed if I purge nautilus and with all its no longer used dependencies (is it used by another gnome-based package)? – aleskva May 10 '16 at 17:26

    in my case it still doesn't work. I had to execute sudo nautilus ... – bogdan.rusu Nov 12 '16 at 14:25

For me terminating the running nautilus process and restarting it worked.

ps awx | grep nautilus

I found the process id and then terminated it with

sudo kill -TERM <id>
  • That is what sometimes happens on my Ubuntu GNOME 16.04 and your solution is exactly what I've needed. – hata Oct 30 '17 at 14:30

    Or you can kill it from process monitor. – Vicky Dec 9 '17 at 14:53
  • wow.. this piece of code helped me. Thanks – MagePsycho Jan 23 '18 at 11:43

    Commands didn't help me (or maybe I used the wrong ID), but killing nautilus from the system monitor did it for me. Thanks! – Nat Naydenova Mar 25 '18 at 19:29

killall nautilus

will kill all instances.
