尝试安装任何东西时出现“不受信任的软件包可能会危及系统的安全”

  • 772

我在新计算机上新安装了 Ubuntu 10.04。我正在尝试在其上安装我需要的应用程序（我的旧计算机坏了，我必须将其送去维修）。我已经设法安装了 texlive，但是我无法安装其他任何东西。我要安装的所有软件都是我之前在旧计算机上成功安装的软件（使用相同版本的 Ubuntu）。我不明白为什么终端会发出这个警告（对不起，终端会说一半英语，一半波兰语，但我希望这已经足够了）：

maria@marysia-ubuntu:~$ sudo aptitude install emacs

我也尝试安装其他编辑器，结果相同。当我决定我可能确定我要安装的软件包是安全的时，我最终输入了“是”。安装成功结束，但编辑器不理解 .tex 文件（并且 .tex 文件本身已知是好的）：

this is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

restricted \write18 enabled.

?

更重要的是，我意识到在 Synaptic Manager 中没有任何包被标记为 Canonical 支持的包......

有小费吗？提前致谢。

使用后update，几乎没问题。我已经成功安装了 3 个应用程序（texlive、texworks 和 ekg），Synaptic 显示“受 Cannonical 支持”的图标。但连接问题仍然存在。

我已连接到 Internet，我可以使用聊天，但有时我无法打开任何网页。我不确定这是否是同一问题的一部分，或者是否解决了另一个问题，而另一个问题我应该单独写一篇文章。

使用更新后的 apt 源列表：

似乎变了，但这是我唯一能理解的。

谢谢。

  1. Best Answer

    尝试更新数据库

    sudo apt-get update

    如果之后您仍然看到警告消息，请提供您的存储库列表

    grep -IRH '^deb ' /etc/apt/
    • 8

  2. 如果您刚刚安装了 Ubuntu，并且没有添加任何存储库，请更新软件包列表并升级软件包：

     sudo apt-get update
 sudo apt-get upgrade

    建议在安装其他软件包之前先更新系统（至少在第一次安装之后）。CD 的内容可能已过时。

  3. 我不是 100% 确定，但看起来你缺少一堆 gpg 密钥。为了解决这个问题，我将安装launchpad-getkeys，它将导入系统上所有缺失的密钥。

    要安装启动板-getkeys，您需要先添加一个 ppa -什么是 ppa 以及如何使用它们ppa 行是ppa:nilarimogard/webupd8

    然后您可以安装启动板-获取密钥首先键入此

    sudo apt-get update

    那么这个

    sudo apt-get install launchpad-getkeys

    最后用这个命令运行

    sudo launchpad-getkeys

    最后我会在导入密钥后运行另一个更新。

    sudo apt-get update

    希望这可以帮助
