我仍然不确定这是否能解决我的打印问题，但在发现后，我试图将 Java 恢复为 32 位版本我的 64 位 Java 无法与 CUPS 通信.（Ubuntu 15.10 64 位）
sudo apt-get install openjdk-8-jdk:i386
我现在有一个 32 位 Java。java -version返回
openjdk version "1.8.0_66-internal"
OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)
OpenJDK Server VM (build 25.66-b17, mixed mode)
但我似乎无法安装 32 位的 OpenJFX
sudo apt-get install openjfx
或者
sudo apt-get install openjfx:i386`
openjfx安装 64 位版本，使其对 32 位程序不可见。
The following NEW packages will be installed:
libgconf2-4 libopenjfx-java libopenjfx-jni openjdk-8-jre
openjdk-8-jre-headless openjfx
openjfx:i386需要libopenjfx-java:i386“无法安装”

我试过sudo apt-get install libopenjfx-java:i386

sudo apt-get update是我读完上述内容后做的第一件事，但我得到了同样的回应
这是我第一次使用:i386，我不知道我还能做些什么来让它工作。有什么想法吗？
