I am just getting started with the yocto project and trying to build an image for x86 architecture to be emulated using QEMU emulator (running on Ubuntu 16.04 ).I am getting the following error while building the OS image.
ERROR: core-image-sato-1.0-r0 do_rootfs: Error executing a python function in exec_python_func() autogenerated:

Build process runs upto almost 90 percent after which this error comes up which terminates the process.What could be the issue ?
当我的主机突然关闭时我遇到了同样的错误,但是在我使用sudo rm -r build/tmp/work/qemux86-poky-linux/core-image-sato/1.0-r0/oe-rootfs-repo/.repodata/
删除.repodata
文件夹后一切正常sudo rm -r build/tmp/work/qemux86-poky-linux/core-image-sato/1.0-r0/oe-rootfs-repo/.repodata/
然后再次构建。
I stopped a build using Ctrl-C and got the python error described in the original question.
The .repodata folder (please see the answer from jmiranda) was empty. So I deleted the oe-rootfs-repo folder and this worked for me.
I get the same issue, but with error "Directory not empty" instead, when building in Docker container. Deleting the destination directory using rm -r, and running the build again, works.
None of these methods worked for me.
I then clean the build using bitbake -c clean mybuildname
and then again made the build and it worked flawlessly, i hope it helps someone.
