Removing Python2 Completely

Removing Python2 Completely

Hi,

I am trying to remove Python2 and it's supporting modules completely from
my Image, as I have moved all my code to Python3 and hence no longer
require Python2. I tried the IMAGE_INSTALL_remove variable but seems to
have no effect. Is there a way I can remove Python2 without much changes to
the layers and through configuration variables only ?

Please point me to the correct mailer if  I am wrong.

Thanks,
Aashik

You can see what is pulling the python2 to the image (using the bitbake 
-g for example).

Which Yocto release are you using? I believe the latest one (Dunfell) is 
already python3 only.

If you want to remove python2 from the image, you need to make sure that 
no other package installed
to the image RDEPENDS (runtime dependency) on it. I would start with 
checking what still pulls the
python2 to your image.

https://www.yoctoproject.org/docs/1.8/ref-manual/ref-manual.html#usingpoky-debugging-dependencies

Also, please reply to the list, not directly to just me.

Thanks,

Now I am able to see only python-core remaining in the RootFS Manifest and
Image size has decreased by nearly 10 MB.

Thanks,
Aashik
