Python2 requirement for imagebuilder

why openwrt imagebuilder (19.07.1) still needs python2?

Because the 19.07 branch isn't migrated fully to Python3 yet.

didn't openwrt actually started to remove python2 apps and libraries beciase end-of-life of python2? but the image builder (not the sdk or compiler tool but the simple pre-built downloader and builder ) is still depending on python2 ?

Yes, in master.

I got a bit confused but I think i know what happened here ""
it seems that because of some distros using python for exe name for python3, now the image builder specifies the python 2 by the name python2.
I think I didnt have it installed and it worked with python as python3.
so maybe the image builder (the simple prebuilt one) doenst actually need python2 and can use python3 too.

I just built a buildbot config against master without python2 successfully.

So the imagebuilder no longer requires Python 2, right? If true, then we need to update the documentation here:

sudo apt install build-essential libncurses5-dev libncursesw5-dev
zlib1g-dev gawk git gettext libssl-dev xsltproc rsync wget unzip python

If you install the python package you will pull python 2. I suggest we change it to python3.
