linux/ubuntu 上的铬 flash EOL

Question

有多个博客介绍了如何使 flash 在 EOL 之前无法迁移的站点或固件控制台在 EOL 后工作。

• 降级到 google-chrome 87.x
• 构建mms.cfg并放入适当的 google-chrome 配置目录

在这个程度上，我想在虚拟机（VirtualBox 6.1.6 上的 Ubuntu 20.4.1）中运行这个补丁，以确保我的实际机器是最新的并且完全打了补丁。 但是我发现补丁在我的 MacOS 主机上有效，但在 Ubuntu VM 上无效。 运行一次按钮永远不会出现，并且网页中的 flash 组件显示下载失败

为了消除潜在的拼写错误 - 我已经使用 YaML 配置文件在 python 中进行了编码。 为什么这在 Ubuntu 上的 google-chrome 中不起作用？
