无法安装不受信任的来源，也无法下载更新信息

我将服务器从最快的服务器更改为主服务器，同时尝试修复软件管理器的问题（不受信任的来源无法安装 FYI），但出现错误。

这是我收到的一个错误：

我尝试了当我使用 PPA 或更新我的软件包列表时，如何修复 404 错误？，但我仍然在软件更新程序中收到不受信任的来源错误。

答案1

  • 首先安装 Y-PPA 管理器：为此您必须下载 deb 包，您不能通过 PPA 安装，因为您无法更新软件列表。
    点击此链接下载 deb

  • 然后打开它并单击高级选项。


Y-PPA 管理器中的高级选项


  • 然后点击第二个选项（尝试导入所有缺失的 GPG 密钥），如下图所示：


Y-PPA 管理器中的 gpgkeys-import

  • 等待一段时间。然后点击第三个选项（尝试修复所有 GPG BADSIG 错误）
    您需要等待一段时间，直到它显示完成的通知！

  • 如果你最近升级了 Ubuntu，则必须点击“Ubuntu 升级后重新启用可用的 PPA”

  • 然后运行sudo apt-get update之后你可以返回到你正在尝试做的事情。
