我正在尝试在 Xubuntu 16.04 上安装 64 位的 BricsCAD v13，但它有几个未解决的 32 位依赖项。除了 libgtk2.0-0:i386 之外，我能够解决所有问题。
为了安装它，我首先运行以下命令来处理 32 位包：
sudo dpkg --add-architecture i386
sudo apt-get update
然后我尝试使用以下命令安装该包：
sudo apt-get install libgtk2.0-0:i386
但终端返回以下错误：

The following additional packages will be installed:

我知道如何恢复正常，以便软件包系统再次正确。但我希望能够安装所述软件包的 32 位版本，以便能够安装 BricsCAD v13，但系统似乎与在两种架构中拥有相同的软件包相冲突。
感谢您的帮助

从错误消息中可以看出，文件冲突仅针对文档文件。
因此，您可以使用以下命令强制安装这两个包：
sudo dpkg -i --force-all /var/cache/apt/archives/libatk1.0-0_2.34.0-1_i386.deb
sudo dpkg -i --force-all /var/cache/apt/archives/libgtk2.0-0_2.24.32-4ubuntu1_i386.deb
最后运行
sudo apt-get install -f
sudo dpkg-configure -a
把所有的事情都解决好。
