我使用的是 64 位 Xubuntu 14.10。如果重要的话，带有专有驱动程序的 Nvidia 显卡。我刚刚跑步apt-get update && apt-get upgrade，所以我应该了解最新情况。我的CPU架构是x86_64。
我正在尝试安装 PlayOnLinux。我添加了 PPAhttp://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu并运行了apt-get install playonlinux。没用。我得到这个输出：
peter@HandOfGod:~$ sudo apt-get install playonlinux

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:
playonlinux : Depends: wine or
wine-unstable but it is not installable
E: Unable to correct problems, you have held broken packages.
apt-get -f install playonlinux没有影响。输出如上。
接下来我尝试了apt-get -o Debug::pkgProblemResolver=yes install playonlinux。这给了我一堵巨大的文字墙，太长了，无法在这里发布。它基本上是一堆broken x depends on y。它反复提到 i386 软件包，这很奇怪，因为我的机器是 64 位的。
apt-cache policy playonlinux给出这个：
playonlinux: Installed: (none) Candidate: 4.2.3-1 Version table: 4.2.3-1 0 500 http://us.archive.ubuntu.com/ubuntu/ utopic/multiverse amd64 Packages
我尝试使用 synaptic 安装来看看它说了什么。
不好。它想要删除大约十亿个软件包，其中许多与 Wine 完全无关。
