# needed to change the ORDER of "apt-get commands" and move the "update-alternatives" for python3
# AFTER the "apt-get remove -y python3.10" cmd, OTHERWISE the symlink to python3
# is broken in the image and the VSCode debugger could not exec "python3" as CMD overwrite
# also fixed a boring "Blinker" blocking error

    # VENV will have their own "preferred/supported/recommended" Python version, as e.g.
    # the "kohya_ss" app, only supports Python up to version 3.10 (but not 3.11)
    #
    # until here we have a broken "Blinker" installation from some base images before,
    # and if we try to "update" "Blinker" for Python3.10 or via e.g. "pip install --upgrade blinker",
    # or "pip install blinker==x.y.z.z", this breaks, as it was installed in an APT bundle,
    # which can not be safely upgraded (= Uninstall/Reinstall)! It breaks as follows:
    # we get a blinker 1.4 uninstall error chained by trying to uninstall "distutils":
    #    8.568     Found existing installation: blinker 1.4
    #    8.782 error: uninstall-distutils-installed-package
    #    8.782 
    #    8.782 × Cannot uninstall blinker 1.4
    #    8.782 ╰─> It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
    # that not only blocks building the docker image, but later also breaks the "kohya_ss" app during setup,
    # which try to install Blinker and Python310-venv from "setup-runpod.sh":
    #   # Install tk and python3.10-venv
    #   echo "Installing tk and python3.10-venv..."
    #   apt update -y && apt install -y python3-tk python3.10-venv
    #
    # Python 3.10 needs to run as Kohya's "official" requirement, and is used in the VENV
    #
    # first uninstall the APT bundle package for "Blinker"
    apt-get remove -y python3-blinker && \
    # then re-install the APT unbundled package of "Blinker back",
    # together with Python3.10 venv, which we need to setup the kohya_ss VENV
    apt-get install -y python3-tk python3.10-venv && \
    # this re-captures back the "python3" alias for Python3.10, but not the "python" alias (stays for Python3.11)
    # the "Python3.11" and "Python3.10" cmds work too
    # global PIP is 3.11, VENV pip is 3.10
