Why is your Python version newer than mine? I cannot seem to find this version of Python in any of the mirrors. Oh, wait! I can see that there's a "python3" 3.9.18 available as a testing version. I don't quite understand how this works though, because when I install it I still have Python 3.9.16. Seems like there are two Python packages: "python3", which has the 3.9.18 test version, and then there's "python39", which only has 3.9.16. The first one just seems to be a meta package, so it doesn't contain anything. So... where did you get Python 3.9.18 from? You mentioned that it also hogs all CPU, so could it be that this is basically a broken Python installation? Patrick
