Hi I know this is an old post but I've been through every forum trying to fix this issue. I need tkinter for my ubuntu virtual machine, I've checked im in the correct python, installed all the packages including the one Robert suggested (though installing from distro so I shouldn't have to). Nothing.. I even tried manually copying the tk8.6 directory into lib and tcl8.6, no effect.
Just:

lewie@lewie-virtual-machine:~/Downloads$ python3

Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> tkinter._test()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.10/tkinter/__init__.py", line 4586, in _test
root = Tk()
File "/usr/lib/python3.10/tkinter/__init__.py", line 2299, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable tk.tcl in the following directories:
/usr/local/lib/tcl8.6/tk8.6 /usr/local/lib/tk8.6 /usr/lib/tk8.6 /usr/lib/tk8.6 /lib/tk8.6 /usr/library

This probably means that tk wasn't installed properly.

incidentally the /tk8.6/ dir only contains "pkgIndex.tcl"
in case that's what's wrong.

Any help would be great

This is strange at the very least. Besides pkgIndex.tcl, there should be
a folder with a lot of support files (scripts, icons, demos,...). It is
basically this stuff:

https://github.com/tcltk/tk/tree/main/library

So maybe the package from your distro is simply broken? Or, the package
from the distro is installed somewhere else, and Tcl picks up a broken
version first and can't find the right version. You can check the path
where Tcl looks for packages like this:

(base) Apfelkiste:~ chris$ python3
Python 3.8.8 (default, Apr 13 2021, 12:59:45)
[Clang 10.0.0 ] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> interp=tkinter.Tcl()
>>> interp.eval("set auto_path")
'/Users/chris/bin/anaconda3/lib/tcl8.6 /Users/chris/bin/anaconda3/lib'
>>>

and afterwards try to load Tk manually:

>>> interp.eval("package require Tk")
'8.6.10'

then this should tell you, which version was loaded:

>>> interp.eval("package ifneeded Tk 8.6.10")
'load /Users/chris/bin/anaconda3/lib/libtk8.6.dylib Tk'
>>>
