Nautilus Won’t Launch – How to Fix Nautilus Not Launching on Ubuntu 16.04

16.04nautilus

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

launch

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])

check

name@machine:~$ nautilus -c
running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory

(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?

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.

Use

sudo apt-get install --reinstall nautilus-data

to install that package again.

Run Dolphin Instead of Nautilus – Step-by-Step Guide

There are several caveats in what you tried to do. I already mentioned the danger introduced by your approach:

Next time nautilus is going to be updated, your dolphin gets overwritten (as your link points there). Same goes for gnome-terminal.

So we figured, this was not a good idea :)

But there are some ways to try working around, so "x" gets run when "z" was requested -- but I'm not aware of any as soon not "z", but "/full/path/to/z" gets called. As long as it is just "z":

creating an alias for z, like alias z=x (works on a per-user-level -- or globally, depending on where it was defined)
creating a "replacement" for z in a location mentioned in the PATH before the location the real z resides in

A little more details on the second approach. Taking your original problem, you want to have dolphin executed whenever nautilus is called upon. You already found nautilus at /usr/bin/nautilus. Now let's (probably correctly) assume your $PATH contains (in this order) /usr/local/bin:/usr/bin -- so you see /usr/local/bin would be searched before /usr/bin. So we simply create a shell script /usr/local/bin/nautilus with the following content:

#!/bin/bash
/usr/bin/dolphin %$@

So what will happen? If you (or some script/program/daemon/...) invokes nautilus, this will execute /usr/local/bin/nautilus (as this is the first "nautilus" found in the PATH), which simply starts /usr/bin/dolphin -- voila! But if the "whatever" uses the full path, this won't work.

So you say: Hey, why didn't Izzy say "just do a ln -s /usr/bin/dolphin /usr/local/bin/nautilus?" Sure you can do that -- and it will work the same. But using a script as shown may come in handy if you need to introduce additional parameters which are not passed with the original call. With above script, dolphin simply gets passed the same parameters the original call used (%$@). But you can play around with things in the script, replace parameters, etc. As for your current problem, the link would be enough (as long as nautilus doesn't get called with the full path).
