Debian 测试 - apt 软件包在安装 Virtualbox 6.0 或 6.1 时存在未满足的依赖项

Question

这可能不是问这个问题的最佳地点（如果不是，请把我指向其他地方）但是我在尝试在 Debian 测试系统上安装 Virtualbox 6.0 或 6.1 时遇到了未满足的依赖关系问题。

我的猜测 - 虽然我不知道是不是这种情况 -libvpx5是不是testing由于某种原因不可用。

sudo apt install virtualbox-6.0

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 virtualbox-6.0 : Depends: libvpx5 (>= 1.6.0) but it is not installable
                  Recommends: libsdl-ttf2.0-0 but it is not going to be installed
                  Recommends: linux-headers-generic but it is not installable or
                              linux-headers-generic-pae but it is not installable or
                              linux-headers-686-pae but it is not installable or

                  Recommends: linux-image but it is not installable
E: Unable to correct problems, you have held broken packages.

这是我的 /etc/apt/sources.list

# virtualbox
deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian buster contrib

我认为添加buster是在这里做的正确的事情，尽管我正在跟踪测试分支。

我应该如何解决这个问题，或者真的无法解决？

Answer 1

该 VirtualBox 软件包适用于 Debian 10，而不是 Debian 测试（即便如此，它确实是为 Ubuntu 设计的）。有两种方法可以解决这个问题：

• 将 Debian 10 添加到您的源代码中 —libvpx5在那里可用；
• 将 Debian 不稳定添加到您的源代码中，这在您跟踪测试、启用contrib和安装可用的virtualbox软件包时无论如何都是一个好主意。

要执行其中任何一项，请编辑/etc/apt/apt.conf添加一行，指定您的默认值是 Bullseye（当前的 Debian 测试）：

APT::Default-Release "bullseye";

然后将额外的存储库添加到/etc/apt/sources.list或 中的新文件/etc/apt/sources.list.d；例如在/etc/apt/sources.list你可能最终

deb http://deb.debian.org/debian bullseye main contrib non-free
deb http://deb.debian.org/debian unstable main contrib non-free

如果您要跟踪 Bullseye 和不稳定。
