I had trouble with my main rig, see other thread. I had to stop at step two of the safer method. Some packages just don't support 3.13 yet. It seems to be quite a few too for me. Mostly Kicad and such as that. On my old rig, the one with opencv problems, I had trouble with it too. I had to stop it at the same spot as my main rig. Depending on what you have installed, it may be easier to get to step two of the safer method and then stop. Give it a few weeks or so and then try step three and see if it completes or if you only have a few per package exceptions for package.use. From what Eli posted, it is safe to do so. It just means you have a extra python version installed and a couple lines in package.use. It is better than having a system that can't update cleanly. Then again, I'm still arguing with opencv on my old rig. May need a bigger hammer and a mean look. o_O Just thought it may be a option you want to consider. Dale :-) :-)
