The python 2 install on my ubuntu 17.10 install works fine, Tkinter is imported without errors, but on the python 3 install, import tkinter fails.
I've tried to reinstall python3-tk and reinstall python3 altogether.
The OS is ubuntu 17.10 with the default GNOME desktop environment, and the python 3 version is python 3.6.3.
I'm out of ideas on how to fix this. A lot of my projects rely on tkinter for the interface, and I can't make it work.
