  python-deps:

    14

    # This part provides all python2 dependencies, including interpreter

    15

    # More particularily, it builds latest PIP supporting python2 from git

    16

    # and uses it to collect and buid other Beremiz dependencies.

    17

    18

    # rational:

    19

    #  - python plugin doesn't support python2 anymore on core20+

    20

    #  - attempts to get python2+pip+virtualenv in a core20 based snap failed
