我正在运行 Ubuntu 19.04 并尝试按照此处的说明进行操作：
IcedTea-8 无法运行任何 jnlp 应用程序（可能是由于 openjdk-11？）
当我做
wget http://mirrors.kernel.org/ubuntu/pool/main/o/openjdk-8/openjdk-8-jre-headless_8u212-b03-0ubuntu1.16.04.1_amd64.deb
它说

答案1
如果你直接访问你使用的链接wget，显示 404，这就是为什么你一定会收到这个错误。列表中的第三个链接似乎也不起作用，所以也许你应该openjdk jre使用其他方式或通过运行
sudo apt-get install openjdk-8-jre
