我正在尝试从 Ubuntu 22.04 连接到 iDRAC 8 虚拟控制台。Icedtea 已安装：
icedtea-netx:
Installed: 1.8.4-1build1
Candidate: 1.8.4-1build1
单击 iDRAC 中的控制台链接上的启动时，将下载 .jnlp 文件。Iced tea 尝试打开，但每次都会挂起：
我在 Iced Tea 网络控制台中启用了日志记录，以下是输出：

如果我尝试使用已安装的 openjdk-19，则会出现以下情况：
我以前从来没把 .jnlp 文件设置为可执行文件。不过，这篇文章主要关注的是 icedtea。
截至目前，由于此问题，我无法远程管理我的 iDRAC。
这里可能发生了什么事情，导致 icedtea 挂起？
答案1
最后，通过删除所有内容，然后安装 OpenJDK 8，再安装 icedtea，终于让它正常工作了。是的，icedtea 安装了 openjdk-11，但事先安装的 8 似乎可以正常工作。
sudo apt purge icedtea*
sudo apt purge *openjdk* -y
sudo apt purge oracle-java11-* -y
sudo apt autoremove --purge -y
sudo apt update && sudo apt install openjdk-8-jdk
sudo apt install icedtea*
验证安装：
$ update-java-alternatives -l
java-1.11.0-openjdk-amd64 1111 /usr/lib/jvm/java-1.11.0-openjdk-amd64
java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64
关闭浏览器或者重新启动。
现在转到您的 iDRAC 启动控制台链接并尝试一下。
