image_types.bbclass:

ln -s ${IMAGE_NAME}.rootfs.${type} ${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.${type}

The problem is that $type=ubifs but the extenstion the ubifs image
generates is ubifs.img:

IMAGE_CMD_ubifs = "mkfs.ubifs -r ${IMAGE_ROOTFS} -o ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.ubifs.img ${MKUBIFS_ARGS}"

and we don't support generating image types where the image extension
and the type name differ...

I'd guess the quick fix is s/ubifs.img/ubifs/ in the above...
