我正在尝试在 ubuntu 12.04 上获取用于 Chromium 的 Flash，但当我尝试从终端安装它时，sudo apt-get install pepflashplugin-installer出现了错误对话框
Failure to download extra data files
The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.
pepflashplugin-installer
The download will be attempted again later, or you can try the download again now. Running this command requires an active Internet connection.
单击立即运行此操作没有帮助，因为它只是失败并再次打开对话框。
sudo update-pepperflashplugin-nonfree --install并且由于“未找到命令”而无法继续。

我今天尝试重新安装，sudo apt-get --reinstall install flashplugin-installer突然安装成功了。
