Install tkinter in python3.6 on Ubuntu

run from terminal:

sudo apt-get install python3.6-tk

or just reinstall completly:

sudo apt-get install python3.6

Python version 3.6.4 (Ubuntu 18.04 LTS)

sudo add-apt-repository main

sudo apt-get install python3-tk

I faced a similar problem to yours, I am giving the details of it and how I solved it.

On Ubuntu 16.04 LTS, I have Python 3.5.2 and Python 2.7.12 but I would like to experiment Python3.6 (for various reasons like this one, for example). So I relied on this post:

sudo add-apt-repository ppa:deadsnakes/ppasudo apt-get updatesudo apt-get install python3.6

When I tried to run a module using tkinter, I got this error message:

Traceback (most recent call last):  File "/usr/lib/python3.6/tkinter/__init__.py", line 37, in <module>    import _tkinterModuleNotFoundError: No module named '_tkinter'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "bill.py", line 3, in <module>    from tkinter import Canvas, Label, Tk, StringVar, Button, LEFT  File "/usr/lib/python3.6/tkinter/__init__.py", line 39, in <module>    raise ImportError(str(msg) + ', please install the python3-tk package')ImportError: No module named '_tkinter', please install the python3-tk package

I tried to install tkinter as the message above asks:

Obviously, I still can not use tkinter for Python 3.6. How to fix this problem?

My first blind attempt did not work:

sudo apt-get install python36-tkReading package lists... DoneBuilding dependency tree       Reading state information... DoneE: Unable to locate package python36-tk

The second one works:

And that solved my problem:
