错误报告给你安排得明明白白的，请你先 Try installing ca-certificates 好吗？
«提问的智慧»读一读，错误报告自己至少也要逐词读过吧？ 错误报告都不读，Emmm，以后还怎么写 bug ？ --- 说楼上是猪队友不过分吧？ |

楼主你可以参考一下这个： https://askubuntu.com/questions/792354/ubuntu-docker-container-update-ca-certificates-command-not-found
我推荐你这样做： 1. 恢复 apt 配置到初始的情况 2. apt update 3. apt install ca-certificates 4. 现在你可以切换到 https 版本的 apt 配置了 --- @msg7086 #4 这题真的好难，你说得对，我终于推断出来楼主尝试安装过 ca-certificates 了 我是猪队友，好了吧？ |

事实上你需要的是先用 http 源，然后安装 apt-transport-https，这之后就可以改用 https 源了。
出现这样的问题是因为 Debian 的 apt 默认没有 https 支持的原因 |

事实上 Debian Buster 开始你已经不需要再特意下载 apt-transport-https 了，这个问题的关键是没 ca-certificates，但修改 sources.list 文件后你又没办法下载这个包了，所以五楼说的是对的
