I have installed GIMP2.10 in my Ubuntu 16.04. I have the following simple plug-in:

#!/usr/bin/env python



# Tutorial available at: https://www.youtube.com/watch?v=nmb-0KcgXzI

# Feedback welcome: [email protected]



from gimpfu import *



def sample_plugin(image, drawable):

    # function code goes here...

    print("hello")





register(

    "python-fu-sample_plugin",

    "SHORT DESCRIPTION",

    "LONG DESCRIPTION",

    "Jackson Bates", "Jackson Bates", "2015",

    "sample_plugin",

    "", # type of image it works on (*, RGB, RGB*, RGBA, GRAY etc...)

    [

        # basic parameters are: (UI_ELEMENT, "variable", "label", Default)

        (PF_IMAGE, "image", "takes current image", None),

        (PF_DRAWABLE, "drawable", "Input layer", None)

        # PF_SLIDER, SPINNER have an extra tuple (min, max, step)

        # PF_RADIO has an extra tuples within a tuple:

        # eg. (("radio_label", "radio_value), ...) for as many radio buttons

        # PF_OPTION has an extra tuple containing options in drop-down list

        # eg. ("opt1", "opt2", ...) for as many options

        # see ui_examples_1.py and ui_examples_2.py for live examples

    ],

    [],

    sample_plugin, menu="<Image>/Filters")  # second item is menu location



main()

I saved this as a .py file and placed it at /home//.var/app/org.gimp.GIMP/config/GIMP/2.10/plug-ins

This folder path is already listed in Edit->Preferences->Folders->Plug-ins

When I restart GIMP, I'm not able to find this sample_plugin in the Filters menu. Not able to understand why. This is my first GIMP plug-in
