apt update 错误仅适用于非官方 ppas

在代理服务器后面的计算机上（适当配置我希望），从 Ubuntu 18.04 LTS 升级到 20.04 再升级到 22.04 后：

  • 从官方 Ubuntu 存储库更新/升级工作正常，因此我认为网络配置没有问题
  • 但是更新任何非官方 PPA 总是会出现错误，见下文。

这看起来像是网络错误，对吧？如果是这样，为什么只有非官方 PPA 才会发生这种情况？有什么建议可以解决这个问题吗？

答案1

感谢@nobody 的评论，将在中发现的失败的非官方 PPA 地址中的所有https替换为解决了大多数存储库的问题。http/etc/apt/sources.list.d/xxx

这种方法至少适用于三种不同的 PPA，但 owncloud PPA 仍然会出错。可能存在具体错误与他们的服务器。
