new install, now cant import tkinter

just following up in case anyone else follows this thread - unfortunately I was not able to fix it until I did a reinstall from here:

forum.linuxcnc.org/9-installing-linuxcnc...onic-beaver-mint-iso

...which is a great iso

I just ran into this as well. The problem seems to be that /usr/bin/update_ini has been (partially) updated for python-3, but is still set to use python-2.7. I modified the file and got it working again. See the attached patch file.

Edit: Apply like this:

I ran into the same issue 10 days ago, apparently now there is a proposed solution for it.

I couldn't solve it and I downgraded to 2.8.0 again
.

Yes, good advice. I've opened an issue now: github.com/LinuxCNC/linuxcnc/issues/881

I installed Beagle's Mint ISO build master from source yesterday and this was one missing dependency which stalled me. I think
sudo apt-get install python3-tk
sudo apt-get install python-tk

Fixed it.
Just not sure on the second one. It might have been python2-tk. I just guessed we'd need to do something for python2 as well.
So I guessed the dependency.

Not related but the only problem I have is the linuxcnc chooser it too hard to read with squashed up text It would be nice if the column was resizable.

Update: 26 Aug 2023
Phill Carter proved it works in 2.9.0-pre mumble
Thanks Phill

Hello, on linuxcnc 2.8.4 ,
I cannot load Jepler's teachin.py
and
reloading python3-tk then puthon-tk did not get rid of 'no module anemd tkinter'
both modules show up to date
"python3-tk is already the newest version (3.7.3-1)."
"python-tk is already the newest version (2.7.16-2)."
yet jeplers teachin.py gets error
"Traceback (most recent call last):
File "/home/tomp/linuxcnc/nc_files/teachin.py", line 27, in <module>
import tkinter
ImportError: No module named tkinter
"

EDIT:
this is a bitch
python 2.nnn uses Tkinter
python 3.nnn uses tkinter
note the capital T vs lowercase t
also, most of the calls are different in format
and if you try to search  Tkinter vs tkinter,
the web will pften hand you the wrong info despite quotes
Here is a good reference for python 2.nn's Tkinter
www.geeksforgeeks.org/create-first-gui-a...sing-python-tkinter/
but beware opf 'signup' nagging
To learn more on your own...
run      python2.nnn ( likely default for Linuxcnc users )
then    import Tkinter
then   print(dir(Tkinter))        to get a list of all the keywords in he lib
then   help(Tkinter.wordofinterest))        to learn more about a function
Be very wary of any code on web untill you can recognize which T/t kinter is used

I womder if a python2/Tkinter or pyton3/tkinter file could be on a tab?
I originally used a floating pane  using python3/tkinter file for a project.
Then I thought  , hey,  embed that in an axis side panel or tab.
That began the trip here to 'embed py-mumble in a tab' realm.

The control panel created has no hal pins, no hal conmnections.
Yet it controls/reports on hardware.
It controlls stuff used while machining but not under LCNC control.
Its very independant, just close at hand.

I attacj an example pyTk cpntrol pane
( requires a /dev/ttyACM0 device connected
... any arduino with a dip 328p will do , no sketch required )

just thinking out loud
