tkinter on redhat (and testing of tkinter) #5
Description
for Ubunut, there is a python3.x-tk package available for 3.6-3.8 (via deadsnakes repo).
However, this is not the case for base yum in redhat:
centos8:
[root@instance ~]# yum search tkinter

Current;y I a'm "falling back" to just install python3-tkinter if python3x-tkinter fails, but I don't know if that will actually work.
Ideally we would also test that tkinter is working on all distributions.
This is tricky though, because really you need a display:
