我一直在尝试在 Odroid XU4 上设置英特尔 realsense D415 并继续遇到同样的错误。当我通过https://github.com/IntelRealSense/librealsense/blob/development/doc/distribution_linux.md上的命令时，当我尝试 sudo apt-get update 时会弹出以下错误

我已经尝试过 --allow--unauthorized （不记得确切的语法 atm ），即使我也读过它只适用于 apt-get upgrade （而不是更新）。那没起效。还尝试了一个全新的形象。我已经能够毫无问题地在我的 ubuntu 笔记本电脑上运行安装。我也一直在尝试手动添加 repo，但无法弄清楚如何添加。
