For python-six there is python3-six. Both are addons. Can python3-six replace= python-six? Both python-six and python3-six appear to be the same source file but just a = different version number 1.10.0 vs 1.14.0 and they have a different PROG name= . Searching in the git repository I found spice refers to needing python-six = to be built but it is not mentioned in the spice source install instructions = under either mandatory or optional dependencies for building. For python-docutils there is python3-docutils. They again appear to be the sa= me filename but different versions. python-docutils is version 0.12 and is a = core program. python3-docutils is version 0.14 and is an addon. Current versi= on is 0.17.1 Could python3-docutils be made into a core program and updated and python-doc= utils removed? There is python-setuptools and python3-setupttols-scm. These do look to be di= fferent files. Both are addons and grepping in the git repository neither are= dependencies for any other package as far as I can find. Python-setuptools a= lso appears to be a very old version of setuptools at 0.6c11 and the installa= tion is running a .egg file via the bash command. Can python-setuptools just be removed without creating an equivalent python3 = version or is it being used/required somewhere that I have been unable to ide= ntify? Regards, Adolf.

I would like to aim for Core Update 158 and remove as much stuff as possi= ble - if we can everything - and then remove Python 2 in the update after tha= t. If anyone has any custom scripts or applications, people will have some ti= me to migrate away. > > Best, > -Michael --===============0404248438282910898==--
