Thanks I saw your post. I get that you can install stuff on your own, but then what is the point of using a custom distribution? You might as well just use Arabian and customize it yourself. For me the biggest benefit of using DietPi is the fact that it is meintained and I can trust it’s stability and don’t need to worry about comparability, etc.
I think I understand your point. Are you saying that the request would make more sense for Python 3.5, since that is currently stable? I am fine with that as well.
So is it possible to make Python 3.5 the default version in DietPi?
Can’t guarantee everything is working, but you can give it a shot.
Best practice is to use a new or other sd card to test and store the old working sd card installion aside.
