Where do I put them? I don't "do" python - this is double dutch to me. Hello. The "Safer upgrade procedure" in https://www.gentoo.org/support/news-items/2025-03-24-python3-13.html works for me like a charm. yes, looks funny for some people, if in /etc/portage/package.use/python there is something like */* PYTHON_TARGETS: -* python3_12 python3_13 */* PYTHON_SINGLE_TARGET: -* python3_12 But that is right. My old file consist of: */* PYTHON_TARGETS: -* python3_11 python3_12 */* PYTHON_SINGLE_TARGET: -* python3_12 so I start as mentioned in the news with emerge -1vUD @world emerge -a --depclean (I always take care and in doubt don't delete) Then change to */* PYTHON_TARGETS: -* python3_12 python3_13 */* PYTHON_SINGLE_TARGET: -* python3_12 and repeat with emerge. Finally change to */* PYTHON_TARGETS: -* python3_13 */* PYTHON_SINGLE_TARGET: -* python3_13 and repeat. It works for me and looks very straight forward. I got a non-systemd system and not that much packages. Hope you got a clean emerge @world at the beginning. Frank
