There is a circular dependency in the master branch of the layer index: https://layers.openembedded.org/layerindex/branch/master/layer/meta-oe/ https://layers.openembedded.org/layerindex/branch/master/layer/meta-python/ meta-pyhton requires meta-oe, meta-oe requires meta-python. This is fundamentally broken and what is triggering the problem. Obviously I can resolve this in the software and say it's met from a dependency standpoint -but- when constructing things which one comes first? Or is that simply undefined? 84571 4 mark.hatle 2019-08-01 20:40:44 +0000 Fix sent to bitbake-devel. We now detect and abort the dependency processing (with a warning) when we encounter circular dependencies. 84581 5 bluelightning 2019-08-04 22:27:37 +0000 Hmm, yes - meta-oe should not be depending upon meta-python. I don't know how it came to be there, but I have now removed it. 85045 6 mark.hatle 2019-09-23 17:59:28 +0000 Checked in: https://git.openembedded.org/bitbake/commit/?id=d6155d095513be3f500d089c4ed4c4b89949d560
