Hi Chris,

I suspect some renaming is missing on the oecore side. We have this
error on all builds:

Running '. ./init-build-env; bitbake world -k' with output to /srv/pokybuild/yocto-worker/qemux86-world-alt/build/build/command-1-build-targets.log in /srv/pokybuild/yocto-worker/qemux86-world-alt/build/build

AttributeError: module 'bb' has no attribute 'fetch2'. Did you mean: 'fetch'?

Can you have a look at the issue?

Thanks,
