The poky repository master branch is no longer being updated.
You can either:
a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs
b) use the new bitbake-setup
You can find information about either approach in our documentation:
https://docs.yoctoproject.org/
Note that "poky" the distro setting is still available in meta-yocto as
before and we continue to use and maintain that.
Long live Poky!
Some further information on the background of this change can be found
in: https://lists.openembedded.org/g/openembedded-architecture/message/2179
