这看起来好像没有起到什么作用...但为了以防万一，我们还是尝试再次更新：

答案1
您可以轻松删除 VirtualBox 存储库。使用软件和更新 GUI，或运行
sudo rm /etc/apt/sources.list.d/virtualbox*
如果您从 deb 文件安装了 VB，此命令将起作用。如果您手动添加了源，则需要找到源所在的位置，例如/etc/apt/sources.list。
答案2
这不是关于一个名为virtualbox（或virtualbox-6.1或类似的）的包，而是关于存储库提供这些套餐。
存储库中的软件包可以进行加密签名。要检查这些签名，apt需要公钥与存储库关联。设置存储库时，您没有为其正确配置公钥。这就是apt抱怨的内容：

有两种方法可以解决这个问题：如果您想继续从此存储库使用 Virtualbox，则需要提供apt存储库的公钥。或者您可以删除存储库，据我所知，这就是您想要做的。
为此，您需要查看已配置的存储库列表并删除相应的条目。它应该/etc/apt/sources.list直接位于 中，或者位于 中的单个文件中/etc/apt/sources.list.d，具体取决于您最初添加存储库的方式。
