I recently added the the Macbuntu theme in my Ubuntu 16.04 from the site [Noobslab][1], In am learning GTK+ for Python too (PyGTK), earlier when I ran the test programs I made run quietly without showing any error in stderr stream but after I installed the theme, I am getting a warning

(radio_button.py:6696): Gtk-WARNING **: Unable to locate theme engine in module_path: "adwaita",
(radio_button.py:6696): Gtk-WARNING **: Unable to locate theme engine in module_path: "adwaita",

For example when I ran the script of radio_button.py.

I want to fix this error, without uninstalling the theme.

I had the same issue

sudo apt install gnome-themes-standard

Fixed the issue.

In order to remove this warning (you can live with it, it is not causing any problem) the solution above did not worked for me. I had to, on top of installing gnome-themes-standard, do the following: $ sudo apt-get install gnome-themes-extra gnome-themes-extra:i386

In my case was the 32 bit architecture version that did the trick.

Ran into the same error recently also. The fix was painless.

> gimp

> (gimp:925393): Gtk-WARNING **: 01:45:23.097: Unable to locate theme engine in module_path: "adwaita",

First, search for packages that might contain the missing item. In this instance, I ran a search for 'theme' and 'adwaita' - the two clues provided in the error.

> sudo apt search themes adwaita

Sorting... Done Full Text Search... Done

gnome-themes-extra/mantic,now 3.28-2ubuntu1 amd64 [installed] Adwaita GTK 2 theme — engine

gnome-themes-extra-data/mantic,mantic,now 3.28-2ubuntu1 all [installed] Adwaita GTK 2 theme and Adwaita-dark GTK 3 theme — common files

tcl-awthemes/mantic,mantic 10.4.0-1 all Dark and light themes for Tk

Second, I installed the packages listed that 'fit the bill'...

> sudo apt-get gnome-themes-extra gnome-themes-extra-data

Reopened the 'offended' program (in this case gimp) and no more complaints.
