环境： Ubuntu 20.04 LTS（5.4.0-77-generic），Petalinux v2020.1（安装无误）
问题：当我在我的项目上运行“petalinux-build”时，它失败了，唯一的错误是：
ERROR: busybox-1.31.0-r0 do_package_write_rpm_setscene: Fetcher failure: Unable to find file file://37/17/sstate:busybox:aarch64-xilinx-linux:1.31.0:r0:aarch64:3:3717bf908126a62e0e2039c4e00aecad811b83830c64890394896af6ab2b4f2e_package_write_rpm.tgz;downloadfilename=37/17/sstate:busybox:aarch64-xilinx-linux:1.31.0:r0:aarch64:3:3717bf908126a62e0e2039c4e00aecad811b83830c64890394896af6ab2b4f2e_package_write_rpm.tgz anywhere.

如果我没有错，这可能是 Petalinux 镜像的问题，但如果是我的错误（例如在配置过程中），我应该怎么做才能避免这个错误？
我知道我可以下载 sstate-cache 并使用本地存储的包进行构建（我将对其进行测试），但在我的工作环境中，首选从远程源获取。
提前感谢您的任何指导或帮助！
