branches in yocto not syncing.

[gfine1]

We had the need to rebuild our source trees as some changes were not getting picked up. 

In the shift to github from codeaurora it seems branches no longer exist in either

Linux source code migration (CAF -> Github) - NXP Community

or using 

repo init -u https://github.com/nxp-qoriq/yocto-sdk -b dunfell

During the repo sync we get this error.

It seems dunfell is not longer available so we tried

repo init -u https://github.com/nxp-qoriq/yocto-sdk -b hardknott

and

repo init -u https://github.com/nxp-qoriq/yocto-sdk -b langfell

with the same result. 

I have combed the community to see if an update was posted.  

Are we working with the wrong repo? If so, what is the correct repo? We tried 

repo init -u https://github.com/nxp-imx/imx-manifest -b dunfell

and it failed as well.
