Thank you @mirzak and @lluiscampos for the support.

I have fetched the source and added the entries to `conf` file as @mirzak suggested to take the beta components.

I got the below error while bitbaking the sumo source:

> | # [github.com/mendersoftware/mender-artifact/vendor/github.com/mendersoftware/go-liblzma](http://github.com/mendersoftware/mender-artifact/vendor/github.com/mendersoftware/go-liblzma)  
> | …/…/…/…/…/…/…/build/src/github.com/mendersoftware/mender-artifact/vendor/github.com/mendersoftware/go-liblzma/reader.go:9:18: fatal error: lzma.h: No such file or directory  
> | compilation terminated.

After couple of search and debugging, I found that this issue is already addressed by @mirzak in [PR](https://github.com/mendersoftware/meta-mender/pull/711) but, it is missing in the sumo branch.

After adding the `DEPENDS += "xz"` in `"meta-mender-core/recipes-mender/mender-artifact/mender-artifact_3.0.0b1.bb"`, this error got resolved and it build successfully.

I think it is better to add the above changes in the sumo 🙂
