由于 Chromium 宣布将抛弃旧的标准（NPAPI），导致原本的 Flash Player 将无法在 Chromium运行，所以决定在 Chromium 中使用 Pepper Flash Player ，这个Pepper Flash Player是通过下载 Google Chrome 然后提取出来给 Chromium 使用的。
目前这个安装器已经收录于 Ubuntu 14.04 官方源（从 Debian源中导入）。
Ubuntu 14.04 用户可以通过以下命令安装 Pepper Flash Player For Chromium：
sudo apt-get install pepperflashplugin-nonfreesudo update-pepperflashplugin-nonfree --install
如果你想使用 Beta 版的 Google Chrome 中的 Pepper Flash Player，那么可以把第二个命令改为：
sudo update-pepperflashplugin-nonfree --install --beta--unverified
如果想使用非稳定版的 Google Chrome 中的 Pepper FlashPlayer，那么可以把第二个命令改为：
sudo update-pepperflashplugin-nonfree --install --unstable--unverified
如果你想卸载这个 Flash Player ，那么请执行以下命令：
sudo update-pepperflashplugin-nonfree --uninstall
