Trying to build minimal linux image with Poky , getting python import error

Question

I’m trying to buil a minimal linux image using yocto, When I try to run command bitbake core-image-minimal I get an error

from collections import MutableMapping, KeysView, ValuesView, ItemsView, OrderedDict
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

I’ve read somewhere that MutableMapping is deprecated in Python3. I tried to point to python2.7 instead, but I still have the same error

sudo ln -s /usr/bin/python2.7 /usr/bin/python
python --version
Python 2.7.18

I’m using poky zeus branch, ubuntu 22.04

Answer 1

Using zeus branch, your OS (Ubuntu 22.04) is not in the list of the supported ones.

Here I can see two options (I think there is more, but they are the most simple ones):

Install a supported OS on your machine (or on another machine)
Use docker

For docker, install it following the official docs for Ubuntu.

Then you can run docker container on your poky folder to execute bitbake commands:

docker run --rm -it -v /path/to/poky:/workdir crops/poky:ubuntu-18.04 --workdir=/workdir
