错误：无法安全地从此类存储库进行更新，因此默认情况下被禁用

Question

我一直在尝试在 Odroid XU4 上设置英特尔实感 D415，但不断遇到相同的错误。当我执行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

odroid@odroid:~$ sudo apt-get update

我已经尝试过 --allow--unauthorized （不记得确切的语法 atm），尽管我也读到它只适用于 apt-get Upgrade （而不是更新）。它不起作用。还尝试了全新的形象。我已经能够在我的 ubuntu 笔记本电脑上运行安装，没有任何问题。我也一直在尝试手动添加存储库，但无法弄清楚如何添加。

403 - 禁止是服务器端错误。您无权访问服务器上的数据。

请更新 /etc/apt/sources.list。
