I can't change themes in my Ubuntu 15.04 after update. It says: 

The following schema is missing
org.gnome.settings-daemon.peripherals.touchpad

I've used the dconf editor but touchpad doesn't appear. Mouse and keyboard setting also doesn't open.

Are you able to use touchpad, mouse etc..? – Ron Apr 30 '15 at 8:26
    
Same issue for me. Very annoying. – John Jul 19 '15 at 2:51

It's a configuration error in UTT. You need to update some configuration files to use:

org.gnome.desktop.peripherals.touchpad

instead of 

org.gnome.settings-daemon.peripherals.touchpad

Just open terminal and type:

sudo -H gedit /usr/lib/python3/site-packages/UnityTweakTool/section/system.py

Then change the following lines so they look like:

  • Line 182: 'schema' : 'org.gnome.desktop.peripherals.touchpad',
  • Line 193: 'schema' : 'org.gnome.desktop.peripherals.touchpad',
  • Line 205: 'schema' : 'org.gnome.desktop.peripherals.touchpad',

Save changes, close gedit and, again in terminal:

sudo -H gedit /usr/lib/python3/site-packages/UnityTweakTool/section/spaghetti/gsettings.py

Change the following line to:

  • Line 114 (in 15.10 its line 120): touch = gnome('desktop.peripherals.touchpad')

Save and exit. UnityTweakTool should now start without problems.

Note:

If you can't find /usr/lib/python3/site-packages/, then you should have /usr/lib/python3/dist-packages/ instead.

Works for me on Ubuntu 15.10, thank you. – Le Gluon du Net Aug 26 '15 at 14:19
    
Perfect . Thanks it works. – Rajat Pandita Sep 16 '15 at 5:58
    
For 15.10, has someone filed it as bug? I will if not. – eudoxos Sep 16 '15 at 10:02
    
This worked for me as well, thanks. – chest069 Sep 25 '15 at 14:36
    
Thanks! This worked under Ubuntu 15.10 as well. Alternatively, one can enter these two command in a terminal window: sudo sed -i "s/org\.gnome\.settings\-daemon\.peripherals\.touchpad/org\.‌​gnome\.desktop\.peri‌​pherals\.touchpad/g" "/usr/lib/python3/dist-packages/UnityTweakTool/section/syste‌​m.py" and sudo sed -i "s/org\.gnome\.settings\-daemon\.peripherals\.touchpad/org\.‌​gnome\.desktop\.peri‌​pherals\.touchpad/g" "/usr/lib/python3/dist-packages/UnityTweakTool/section/spagh‌​etti/gsettings.py" – Sadi Oct 25 '15 at 12:22

The missing schemas are provided by the gnome-settings-daemon-schemas package.

Try to reinstall it with (in a terminal):

sudo apt-get install --reinstall gnome-settings-daemon-schemas

The schemas should now be installed in:

/usr/share/glib-2.0/schemas/org.gnome.settings-daemon.peripherals.gschema.xml

For me, this did not work. Still the same error and the mouse and kb settings still don't open. – fnl Jun 10 '15 at 12:15

I reinstalled as above with no fix. Reading the schema in gedit, I found 'org.gnome.settings-daemon.peripherals.touchpad.deprecated' but not the missing schema itself (no '.deprecated'). Any ideas what's going on here? – beachbuddah Jun 10 '15 at 22:53
    
This issue still exists in Xenial. This solution (minor change - install, not reinstall) fixed it. – Haqa Oct 12 '17 at 12:04
