在安裝 ubuntu-device-flash 之前，您應該確保已啟用 Universe 檔案。來自 Ubuntu 幫助：
可以透過取消註解對應的 apt 行（即刪除行開頭的「#」）來啟用其他軟體儲存庫，例如 Universe 和 Multiverse。對於 Universe，取消註解這些行：
deb http://us.archive.ubuntu.com/ubuntu/ saucy universe
deb-src http://us.archive.ubuntu.com/ubuntu/ saucy universe
deb http://us.archive.ubuntu.com/ubuntu/ saucy-updates universe
deb-src http://us.archive.ubuntu.com/ubuntu/ saucy-updates universe
您可以在 /etc/apt/sources.list 中找到 apt 行：
sudo vim /etc/apt/sources.list
不要忘記檢索更新的套件清單：
sudo apt-get update
