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

(nautilus:4672): GLib-GIO-ERROR **: Settings schema 'org.gnome.nautilus.preferences' is not installed

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


name@machine:~$ nautilus -c

(nautilus:4689): GLib-GIO-ERROR **: Settings schema 'org.gnome.nautilus.preferences' is not installed

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

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.

  • sudo killall nautilus; sudo apt-get install --reinstall nautilus nautilus-data gnome-system-monitor; journalctl -f; nautilus -c

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.

    Or you can kill it from process monitor.

    Commands didn't help me (or maybe I used the wrong ID), but killing nautilus from the system monitor did it for me. Thanks! Commented Mar 25, 2018 at 19:29

    Still works on Ubuntu 20.04 Commented Nov 20, 2020 at 4:40

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)?

    By far the simplest solution. Should be the top answer. Commented Mar 13, 2021 at 4:20
