我正在尝试在Ubuntu 20.10上安装OpenJDK 8和OpenJFX 8.

I'm trying to install OpenJDK 8 and OpenJFX 8 on Ubuntu 20.10.

在Ubuntu上安装openJFX 8总是有些棘手，但我以前可以使用以下SO解答中的技巧来做到这一点:

Installing openJFX 8 has always been a little tricky on Ubuntu, but I used to be able to do it using the tip from this SO answer: https://stackoverflow.com/a/56166582/2423283 That used to work fine (I think I was using Ubuntu 19.something), however it appears that recently 8u161-b12-1ubuntu2 was removed.

有关更多背景信息，我正在通过docker文件在自动化管道中进行安装.这是Dockerfile的相关部分:

For some more background information, I'm installing this via a docker file in an automated pipeline. Here are the relevant parts of the Dockerfile:

FROM my.company.internal.registry:443/ubuntu:latest

RUN apt -y update && \
    apt -y install \
    openjdk-8-jdk \
    openjfx=8u161-b12-1ubuntu2 \
    libopenjfx-java=8u161-b12-1ubuntu2 \
    libopenjfx-jni=8u161-b12-1ubuntu2

这曾经运行得很好，但现在我得到了:

This used to run just fine, but now I get:

E: Version '8u161-b12-1ubuntu2' for 'openjfx' was not found
E: Version '8u161-b12-1ubuntu2' for 'libopenjfx-java' was not found
E: Version '8u161-b12-1ubuntu2' for 'libopenjfx-jni' was not found

到目前为止我已经尝试过的

我尝试在Dockerfile的FROM行中将ubuntu:latest更改为ubuntu:19:10，但是仍然遇到缺少软件包的错误.

What I've tried so far

I've tried changing my ubuntu:latest to ubuntu:19:10 in my FROM line in the Dockerfile, but I still got the missing packages errors.

我尝试仅删除那些版本限制(=8u161-b12-1ubuntu2)，但在安装过程中没有看到任何错误，但是当我编译代码时，找不到JavaFX类.

I tried just removing those version restrictions (the =8u161-b12-1ubuntu2) and I didn't see any errors during the installation, but then when I compiled my code, none of the JavaFX classes could be found.
