Yes, I did already: https://lists.openembedded.org/g/openembedded-core/message/226640 - I believe this should take care of this issue (but I have to admit that currently I struggle executing the selftest on my machine - both inside and outside of docker I get mysterious qemu startup errors). > Thanks, > Mathieu >
